Hello everyone;
As far as I know the Adrenaline skill is ubiquitous in every build ever, and basically everyone buys into scoundrel just for this. Its just too good to pass.
So throw in my humble 2 cents: Turn Adrenaline into a Talent. Something along the lines of "get 2 extra AP for the first turn of the fight.", therefore removing the scoundrel pre-req while still keeping it balanced.
