I felt like combat was too borning, so i allowed to pick any Feat from Golden Edition, I liked how Figter feats worked out like Frenzy or Cleave, but when Clerics or Mages take free healing, it makes everyone invunerable. How do i balance it out? Just remove too powerful feats?
Remove them. Place limits on them. Rewrite them so they are less powerful/better for your group. There are a number of ways to balance things, but you have to decide what type of balance you want and modify things as needed to get that balance.
Of course, IMHO, this is true of "balance" in any RPG. Even if the RAW are balanced, chances are they are only really balanced for the author's playstyle and campaign setting.
