Ha, I know the feeling. Just the sound of a golden gun power up, as I sit in my little bubble of sanctuary, causes me to curse the hunter class. In all honesty, however, being on both sides of that situation and others where one super stops/cancels out another, I'm perfectly okay with it. If there was no way for the other team to pop Our bubble then even I would say it's Op. If you doubt my opinion on that, roll with double defenders in control and bounce of each others special and let the kill, assist and support bonuses generate you another special way before your partners bubble is even done. Granted it's a really cheap tactic, but it's fun as hell when things get real and the other team swarms you with every intention of tea bagging you guys after they finally take the flag. All in all I think that 'knowing' my wod can be popped adds to the fun.
