Charisma - it's an innate spellcaster. And yes it was reasonably effective
There were a couple of options to help, especially once you hit tenth level. But yes you'd tried to avoid that.
To me it does. Some people want to blow stuff up and don't want to deal with pages of spell list.
From my perspective they are the same in a way 3.0 and 3.5 aren't because you could play at the same table at the same time without knowing at all what other people (including the DM) were using. Or even what you were.
Some of it I found great because it opened things up to more players (Knight (simple defender fighter), Slayer (simple hitty fighter), Thief (simple rogue), Elementalist (simple blast mage)). I found the Scout and Hunter great because they were actual Rangers rather than the flavourless killer we got in the PHB - and they were also simple to play. And the Berserker (Barbarian who started as a defender and finished the fights as a striker) was great. Not everything was good - and it would have helped if the interesting classes in Heroes of Shadow (Assassin, Vampire, Binder) hadn't all failed to keep up.
... are you actually serious? Just saying something is "empowerment"? Especially when it's not a very empowering statement.
And it's not as if "Rulings not rules" is a particularly empowering mantra anyway. It means neither more nor less than "You're on your own bucko." It does precisely jack squat to empower DMs - it is the literal level zero baseline.
Now I'll admit that, as
@Charlaquin points out, this is about a thousand times
less disempowering than the 3.X family's "Here is how you must do things including how your monsters must be put together and the dozens of feats you must use and if you don't your players will be able to tell you you are doing it wrong".
But are you literally incapable of imagining anything more empowering than "You're on your own bucko"?
4e meanwhile did actual things to empower the DM that went beyond giving the DM all the power (which they have in 4e as well) and leaving them on their own and telling them to make it up as they went along. 4e provided
tools. (Of course being 4e it released undercooked and with poor presentation that left people confused).
The two obvious tools are the power system and skill challenges. The power system as far as the DM is concerned says "You can do whatever you want - and here is a nice clean way to turn effects with mechanical impact into game language rather than being stuck making it up yourself. You don't have to do it this way but this is a good way to do a lot of things". Meanwhile skill challenges are a scene pacing tool that can be used by absolute newbies to handle things (I speak from experience). Again, the PHB stepped on the presentation. And the monster creation - again it didn't
bind the DM - it provided good benchmarks for what would work well but the DM could break it if they wanted to. (And most did because the early 4e design guidelines weren't dangerous enough).
But fundamentally:
This is how you
must do it <<< "Rulings not rules"/"You're on your own bucko" <<< "You have the power and here are some tools to help"
Except that designing like 5e
doesn't bring immesurable popularity. 5e was doing decently for a while on a nice sensible curve, selling more copies but making less money than 4e (subscription services are a license to make money). 5e then shot into the stratosphere with
Critical Role.
And you not only haven't proven that 4e was the least successful edition of D&D (it was making about six millions a year for WotC a year after the launch of 5e). The least successful edition of D&D was overall
2e - not only was it caught (by White Wolf), it literally brought down TSR. You also haven't answered the basic question:
What would be the point of making a game like 5e when 5e already exists?
The market share of people who like games like 5e is covered by 5e. Why would they buy a different game just like it? The reason Pathfinder sold was that it took a different path to 4e and thus was able to compete by appealing to a specific audience.
Making a 5e clone would have just been shooting themselves in the head.
Except they
didn't fix LFQW. The fundamental problem is still there and is basically unfixable. They just took enough steps to mitigate it that it's nowhere near so toxic.
