Okay, so take all the damage you do at level 15 in satasha over the course of two minutes. 1 or 2k damage.
So, pretend you have to press your full 90 rotation to do that much damage.
Now your 1, 2, 3, is doing 1, 2 and 3 damage. Your biggest hit in your biggest burst, does 200 damage.
Do you really want to rip your heart out, and do your absolute best, to do that little damage?
