All classes
Problem : the stun that can be perma stunned without any possibilities to move out or even cast anything
Possible solution : When getting stunned, put a temporary effect on the character that prevents him to be stunned for a certain amount of time (like giving 5 seconds at least out of stuns), and put the stun duration limit to 10s maximum (can be lowered if still way too strong)
Another possible solution : lower the stun chance overall and the stun stack duration, all crit classes being at 350+% attack speed (so 3.5 attacks per seconds) while having also 50+% stun chance, is way too much, we could lower by half the stun chance while blocking the fact that you can stack stuns, because now, every critter that will attack you will stun you for exemple 6 seconds, but each hit they havbe a 50+% chance to reset the timer and have multiple chars stacking it up, so if you have 4 critters on you, you get 4 times 6 seconds at 50% every hit
Thats what i see could be done
