Because everyone on both sides is tired of it. Bubble stun makes the game not fun. Period. So if we can get teams to play without it, great. And if we have to use it, we use it. But it has pretty much gotten to the point where everyone and their mother is tired of the smash and stun BS. So we avoid it.
We get that you internet heroes on pot5 are the gods of pvp and never ever have issues with bubblestuns and lolsmashers and the rest because your all just that good. Really, we get it. (Sarcasm off) Really tired of having basically every post from someone on your server trying to prove that everyone else sucks. It's gotten old.
I dislike bubblestun. If it was caster only I'd have no issue with it. Now it's just rolling the dice if I see a sorc if it's bubble or not.
