As a lot of you may be aware, it seems that if you start casting a spell at the same time as you get stunned, the cast won't get interrupted and will continue anyways despite being stunned. I know a lot of you will probably say that it's not a big deal, but as a rogue, a class that relies so much on stuns in pvp, and where letting a mage out of stunlock could mean certain death, this bug creates a HUGE disadvantage for our class. When you're chaining stuns, and one stun is about to wear off, it's nearly impossible to time the next stun perfectly so that the enemy has not even a half second where he can start casting a cc, especially with the lag. I'm consistently getting polymorphed, feared, etcetera, during a stunlock, and losing fights that I should have won. I've logged on to my alliance character and asked some of the people who casted while cc'd what it looked like on their screen, and they told me they did indeed cast while stunned.

I feel like a glitch with this much impact would be high priority, but nobody on the dev team has said anything about it, not even that it's impossible to fix.
