idk if only increase HP in arena is enough, because u are burst in 1 cc, fear, knock have moments, if have hp tw u die the same because the damage is insane now, i say this in 3x3, because have classes that have total controll of area, knockdown of ilu is 1 example that can get all area of arena, and can get all of u party easy in knock and delete 1 or 2 in 3 secs and is hard remove cc with meta of broken shell, beyonde other class than burst in cc, templar, ranger, warlock.
