I keep reading about how ability x is spammed toouch and is way to OP.
Streak, WB, cloak, perma block / dodge / shield.
Instead of tinkering around with these abilities, lets just cut to the chase. Its the spamming of these abilities that people had issue with. Well, I guess shields being able to stack is the outlier.
Simple solution suggestion: if you use the same ability within 1.5 secnds it costs 30% more than the previous time. They started doing it already, just make it applicable to everything, you can even reverse some of your other nerfs ( Im looking at you stam regen).

Have a nice day
