The perks unlock pretty early in the game for new players. When they do, they are very strong.
I haven’t seen all the special weapons yet, but looking at the Priest one, 6 life and cleans, vs some of the mastery unlock weapons like Yasmine’s Chalice, and you wonder if the class weapons are suppose to fill niches early to mid-game.
The class traits look strong, but costly to unlock, so I suspect they are balanced for late-game.
