4e contributed to 'player agency' with dailies, which included attacks and in-combat utilities, as you say, and by making flavor text more mutable (which just continued the trends started with 2e kits and 3e description of characters and their gear being less mechanics-dependent). It did not do nearly as much as it could have out-of-combat, though. There were some out-of-combat utilities - the Ranger's 'Crucial Advice' probably being one of the more obvious non-spell examples (there are numerous out-of-combat-aplicable utility spells, but I'm emphasizing where it got it right across all classes).
About what I thought so far.
As far as I can tell, the Crucial Advice power basically lets you make someone else reroll a skill they just failed with a bonus equal to their Wisdom modifier? That's a nice power, and definitely seems helpful outside of combat (though skills are still a weak point for "player agency" in 4e, from my view, as the DC and skill application is still basically all decided by the DM).
So, 5e could do with a lot more of that - player-defineable flavor, pc customizeability, dramatic limitted-use abilities both in and out of combat for all classes - and also with a good deal less /dependence/ upon DM fiat. (Though, not being dependent on it in no way prevents DMs from exercising their perogative to override the rules)
Generally speaking, this is why I like rules-heavy systems. I prefer the rules being open and displayed to most players, and their abilities reliable, so that they know what their chances are (if they know the system) and what risks they're taking (from no chance to sure thing). It's why I wrote this in my "Running a Game" chapter for my RPG under a section titled "Fairness":[sblock]So, the question is, why will some people easily accept a rule in the book, but not a decision made by GM fiat?
That's a good question, and I'll do my best to address it. Many people rely on the rules as a form of support, be it player or GM.
As a player, it lets me know what I can reliably do. If I know that attacking requires me to roll a base attack + Strength roll, and I need to hit their armor class, then I can plan around that. I can attempt to attain a higher Strength, or a higher base attack, or a masterwork weapon, or feats that boost my roll. It lets me know how I can craft my character to play out the way I want it to. For example, if I had in mind a character who is this huge brute that hits people with a giant axe, I probably envision a high Strength character, possibly with a high Constitution. Now, if I found out (through a house rule) that Dexterity is the attribute that covers whether or not I can hit someone, than my concept changes to include a high Dexterity, so I can make use of my giant axe. These written rules give players a strong starting point when determining the mechanical manifestation of the concept of their character. If their mechanical character does not match their conceptual character very much, than they often find themselves distanced from the character, losing that special connection, immersion, or whatever it is that makes that character special and spark in their mind.
For a GM, having the rules to draw on is incredibly comforting when you are learning. After you have played with the rules for a while, you can see the strengths and weaknesses of the system. Having rules in place allows you to cite them when a player disagrees, even if they think it is a bad rule. Of course, it is true that the more you know about something, the more you can break the rules you were taught at the beginning. So, with more experience, it's much easier to break these rules and have an enjoyable experience, but I think that's a fairly universal rule.
As a player, the rules are there for guidance, and as a source of reliable material. You cannot reliably use GM fiat, for even an amazing GM must come up with the mechanical roll for you to use on the fly. You cannot know what the rolling mechanic will be any more than he does. Take, for example, a maneuver to dodge and have two enemies swing at one another. If I wanted to do that, and the maneuver had no mechanics, than I could have no way of knowing that you'd rule it a certain way, for even you have not decided what the ruling is yet (as the situation is only now coming up). However, if it is a set mechanical maneuver, I know I can reliably use that mechanic, and I can temper a character concept by careful use of reliable rules.
As a GM, they are there as a source of incredible guidance, giving you example after example of how the system envisions Dexterity being used, attack rolls being used, Constitution checks being used. The rules help you see the spirit of the game. Rules help indicate the style of game the rules were created for.
When a GM begins to use his granted power to overrule a player, I personally do not immediately buck against it. I'll accept it. If it creates an inconsistent or displeasing game experience, I'll voice my concern, and I'll drop the game if it continues. I will not try to take away that right from the GM, as he has the right to run his game the way he wishes. As a player, I think I should look for someone a little more in line with what I enjoy. Since, really, it's all about enjoyment. And that's the crux of the matter, really. It's about mutual enjoyment, and it's about a consistent gaming world where reliable mechanics are incredibly useful. That's really it. I break or bend rules all the time, and I attempt to do so in a consistent way. Players are expecting consistency in the rules, and the more decisions they can make without direct GM input, the more in control of their own characters they feel.[/sblock]
The DC have decent guidelines, so the burden on the DM is small.
I think this depends on how you run the game. If everything "levels" with you, then yes, the DCs are easier ("this is a Hard task, and we're level 17, so the DC is
X"). However, what if you approach the game more like Neonchameleon (I think) does, where climbing a mundane tree might be a moderate task for level 1's (in his game)? Who decides what level a task is, and what difficulty for that level? The DM. This gives an awful lot of power to the DM, and players have to hope that he remains consistent in his rulings. They have to ask him "what's the DC to do this" if they want to have a good idea of their odds, and then the DM needs to make up what the DC is. This is close to the "Mother May I" style of game that many people feel undesirable (and something that pushes against "player agency").
There /are/ some utilities that give some classes a bit of agency in skill challegnes, like all get in combat. 5e should much more strongly emphasize such options when balancing the classes, so that everybody contributes & has agency in all three pillars.
We'll see how it goes, but while 4e had some "player agency" mechanics, it didn't have a comprehensive system (to my knowledge) that 5e could lift heavily from. While combat is a very strong component of D&D, I'd like to see the other "pillars" expanded upon, and something much stronger than what 4e had (or 3.X, 2e, 1e, etc.) put in its place. Just me, though. As always, play what you like
