I'm all for more feats. But on the issue of 3.5 vs 5th. I think 5th does feats better. (I don't think there was anything good about 4th)
The problem with 3.5 is that there were some feats that were mechanically super powered but otherwise boring and that needed to be countered with other, equally, boring feats.
Trip attack for instance. Successful trip. Prone. Get up. Attack of opportunity + trip attack. Rinse and repeat. Soon a level 6 fighter can defeat a level 40 end boss that hasn't taken the combat stability feat. Boring. (Even their cages are boring)
