Difficulty balance for melee boss fights

Just wanting to give feedback on the Draven boss fight as warrior. I had to go back and over-level and farm mobs to beat this fight and it probably took me way too many tries... I feel like Warrior with 2H specifically is about the one class this fight almost isn't fair to play. Not enough time to get punish in after dodging/blocking attacks and you attack slow and in melee range. Seems like this one maybe needs to be slowed down like a half second on a few of his attacks. Just my two cents.
