I feel little torn right now ...
On one hand, i would like to have some feats ... bcs it would certainly make my playthroughs a lot more interesting ...
On the other hand tho, the list you provided isnt really convincing ... i mean i know its just an example, but i honestly dont quite understand why even limit it ... from this list i would possibly end up with Skilled most of the time. :-/
Yes, i know that every Fighter and Barbarian would likely pick Great Weapon Master ... question is: So what?

Every Sorcerer, or Bard (and likely some Wizards) would at least for EA purposes pick Warlock Initiate aswell.
Quite honestly im not sure what feat would Ranger pick ... possibly Mobile or Weapon Master (if it would still provide Stat incerase).
Im also asking myself if starting with Random Stat rolls (wich was promised by Larian) AND free feat would make our characters too powerfull ...
I mean i totally plan to start my first game as Half-Orc Barbarian with rolled 18Str +2 from Racial bonus ... imagine having feat on top of that seems almost crazy ... on the other hand tho, why not?

I gues it would be +1 from me ... but i wouldnt restrict it, if we would we would most likely end up with passive and dull choices, and then there is no point. :-/
