Use the feats and have fun with 'em. I get their reasoning, and I can accept it, it's just a kind of annoying example of FR simply being 'better' than the core rules......which is something I thought was mostly in the past....so it's a bit of a booo........
Well, if that's the only measure, why not just give everyone except those with good hp and BAB proficiency in every weapon, since it's just going to weaken the party anyway if they actually use those powers?
Actually, It would make very little difference, especially after 1st level. It mostly there to reinforce in the player's mind what role the classes are best suited for.
No, they don't, because a character could take, say, Scribe Scroll at first level and have the exact same effect regardless of the time scale. The cost of EVERY feat is 'you can't get other feats.' Simply dictating a level at which they are to be chosen doesn't increase the COST, it just puts limits on the feat's versatility.
Scribe scroll actually compares quite favorably to most of the regional feats. But in fact at high levels it does poorly in terms of economy of scale for the benchmark combat spells. But that's besides the point. Magic users still have their chains, though they're less dramatic. I'd still rather take spell focus.
Well, I look at it this way. I"m a first level wizard from place who wants to wield a longsword. I can take one of two feats, one of which is Martial Weapon Proficiency, and one of which is the regional feat that gives me all Martial Weapons.......hmmmmmm..............
The regional and thank god i was given that choice. If I want to take a sucky feat, I atleast want to suck in style.
Or, I'm a first level anything from place who wants to boost my saves. I can take one of two feats, either a +2 save feat, or +1 all saves and AC feat.......hm..............
I'd still rather take spell focus.
Luck of Heroes would come in a close second. Wow, I have a choice..should I be crying?
Or even, I'm a first level anything who wants to be quick....I can take one of two feats, Improved Initiative, or a regional feat that gives me +1 to all saves and AC........well, I can always take Improved Init. later......hmmm......
First level anything, bud? If I were a first level fighter I would head immediatly into power attack and great cleave. Once that's done, I'd go for weapon focus, weapon specialization. Oh..and then the dex and int chains (thank god for ability boosting items), because of all that beautiful circumstantial damage. What do you know, I've reached epic and the chains are extended....
See, this "regional feats are more powerful" thing makes players want to choose them, which links them to the world. Helpful. But the benefit to Whirlwind Attack is the same if I get it now, or if I get it in three levels because of my regional feat....that benefit doesn't significantly decrease at higher levels. The regional feats, baring exceptional circumstances, are 'no brainer' feats....you'd be a fool NOT to take it. They seem to have been designed specifically that way.....it makes someone from one region significantly different from someone from another, and makes sure that difference is reflected in the party.
So to reiterate. For those with the feats to afford it its usually better to simply go into another chain. Now is it possible to get to a high enough level, with enough feats wracked up that you would be better now if you had taken a regional feat? Sure, but then regional feats are only unbalanced for a game that goes on a really long time, and even then their impact would be minimal. Stop at any fixed level from 1-20 and I could recommend another feat (with the possible exception of luck of heroes)
.
But if I'm a wizard from place who wants to wield a longsword, what would ever be my incentive to pick up Martial Weapon Proficiency? I would say that any one feat that makes any other feats seem like bad choices in the circumstances in which they would be chosen is 'overpowered.' The +2/+2 feats aren't overpowered in this respect (+10% on two different rolls is certainly a significant advantage when you use those rolls a lot), Improved Initiative isn't overpowered in this respect (+20% to one roll is a big bonus, if you want to avoid being flat-footed), Skill Focus isn't overpowered in this respect (+15% to one roll is a bit weak, but not enough to make it not worthwhile).
Then you must hate power attack, dodge and its ilk, because they are almost always taken in preference to the feats you listed. And by virtue of the fact that you cited the +2/+2s as being worthwhile balance wise, I'd have to question whether or not you've thought this through.
The regional feats in the book shouldn't stand up against cleave or improved trip any more than they have to stand up to whirlwind attack....they should have to stand up to feats without prerequisites, which they are obviously more powerful than.
Uh, no. They should be somewhere inbetween, where the immediate benefit of the feat compensates for the level based delay (which, yes, means that you are less powerful at any given level) in noting plunging into a feat chain. I.e. they should be balanced, which the underpowered skill boosters, martial weapon proficiencies and the like clearly are not.
If that's cool with you, go, have fun. But I think that's bad design-fu.
