There have been a bunch of different good suggestions here. I'd like to note that if one doesn't want to have fighters do martial initiating, then one may want to check out Sir Percival's Bladecraft system which he's still adding options on but is essentially playable in its current form. It is a very original take and seems to help a lot with making fighters feel relevant while still probably not feeling "too Wuxia" for the people who dislike that.
