I am considering the following changes to Fighters and would like to get some feedback:
Hit Die: D12
Extra Attack: 4th, 9th, 15th
Indomitable: Goes from a re-roll to an auto-success.
Champions: 5th level: Free Savage Attacker feat.
Champions: Remarkable Athelete: Add your entire proficiency to Str, Dex, and Con checks that do not already include it. Increase your vertical and horizontal jump by 1X Str Mod for standing and 2x STR Mod for running jumps.
Eldritch Knight: Choose any two schools.
Battle Master: At 7th level, you can expend an additional Superiority Die on a maneuver.
The obvious downside to moving around Extra Attack is that it creates "dead levels" where the fighter gets nothing. E.g. 20th level is now a big fat nothing for the fighter. 5E's design has striven quite hard to avoid dead levels. May or may not be a problem for you in actual play, but it's something to be aware of.
The change to Indomitable looks totally fine to me. Arguably what it should have been in the first place.
The Champions fixes are fine.
Eldritch Knight: choosing any two schools might be fine in isolation, but they're already the strongest fighter subclass, and you're already boosting the base Fighter chassis. I'd recommend against this one.
Battlemaster: seems fine.
Overall, I think the changes you suggest are all right and will probably do about what you think it will for your game (make fighters more popular/awesome), but the combined weight of all of them makes the fighter very different from the base PHB fighter and risks making the Barbarian even worse by comparison than it already is by PHB rules. It won't break your game but it will change it, just as much as handing out powerful magic weapons will or using a DMG rest variant.
That's what I've got to say.
all looks fine to me, except for the free feat.
Yeah, but it's a notoriously weak feat, arguably the worst in the game. Giving out weak feats for free is okay by me. It's not like giving out Heavy Armor Master or Lucky.
