Another thought just popped in my mind... We don't have a clear distinction on what are feats until now...
So I was thinking maybe we could call them "extraordinary abilities", granted every 3 D&D levels. These would be abilities that are somewhat common to all classes (maybe some exclusive) and the player would choose between them. It's a good way to allow very different builds of a same class.

Into L2 they would be chosen at levels:
01
12
24
36
48
60
72
84

(So a character would have 8 extraordinary abilities)
So if this is something everyone agrees would be cool, we will need more brainstorming... Thinking up these abilities...
