I personally think bull need more time between casting some spells and at least 5% less dmg , cmon if u healer in this tight space ur fdup !
I will always need for more classes in the game... Monk Kung Fu Khajit - with martial art staff and straw hat, Alchemist - throwing bombs and potions , Bard as support rather then healer, and Arificer and Arifact collector of alyed and dwemer ruins
