I’m not sure how should I enjoy playing arena if I sit in cc all the time.
Certain classes have cc that are very long and reset really fast.
And if 2 of these classes are against you in arena, there is no gameplay. You just sit and watch how you or your partner gets killed.
There should be global cc cooldown. For example: Poly 9 sec + Succubus 4 sec. Not 9+9 sec.
