Guild Wars 2

Due to yesterdays bug where power block (which is now, thanks to the nerfs utterly useless) went through defiance, I had the joy of playing an interrupt mesmer in PvE, namely in fractals, and it was hilarious. I never had this much fun since launch. I understand that it was OP but if I wanted to play an interrupt focused build again I could interrupt one attack every 45 seconds-1min. If I focus on dmg instead I just get it done quickly and don’t even need the interrupt.
A defiance rework would make the game a lot more interesting and this would really change the zerk meta to a zerk+CC meta.

I know Anet likes kitten fixes, as seen countless times at the illusionary warden, so why not start off by giving defiance stacks a cooldown so they get removed over time?
