Agree @TreyRex92. While I am not sure where the precise percentage for that happy medium lies, I agree that removing the no stamina cost boon entirely was overkill. Perhaps let me open the bidding with only 50% stamina drain on the next hit after a dodge roll. Perks for level 20 attributes should be powerful and meaningful, not inconsequential.
It was not just the Rolling Thrust perk which was decimated by that headlong series of nerfs. The once proud Sword of Crom was transformed into weak generic rubbish, with the durability of brittle petrified wood. Because after all, when we hear the word ‘Crom’ we all automatically think ‘something that breaks easily’ dont we.
