Spells: Whirl Till You Hurl

[Bkab]

I dunno if it's supposed to be working like this, but I fought an enc today who was blue to me and I had 55 mr at lvl 19 and he managed to keep me stunlocked the whole fight with whirl. didn't resist it once, and it lasted about 8-10 seconds. even when it ran off and I could move I still couldn't cast any spells, it acted like I was silenced. Just wondering if its working properly.
