And if they also add talent trees, then we get twice as much, since talents are conceptually the same as feats, only using a different mechanics.
Maybe feats will have all their prerequisites redesigned, so that they require still a minimum level and some minimum ability scores, but effectively eliminating "feat trees", and then trees will exist only for talents (which could be designed specifically for classes).
I used to like the concept of feat trees, but after a while it's too limiting. E.g. all fighters with whirlwind attack have the same 4-5 feats that are its prerequisites. I think it'd be better if a fighter that wants WWA could only get WWA and not other stuff which it's not used afterwards.
