I understand the sentiment of changing 5e to be more customizable from Larian but this definitely the wrong way to do it.
Character identity is built through feats, one thing that 5e did to minimize the Ivory Tower and just add the always right choices was to make feat progression much slower and have a really limited pool of feats. Larian could had changed the feat economy through leveling and add a pool of feats that remove certain limitations from classes like Barbarian can only rage with certain gear limitation, casting spell conditionals, new ways to crowd control that is not limited to only spells(But Larian was on point with adding weapon maneuvers to each weapon type).
