I'm playing a rogue on the Xbox and have noticed a drastic reduction in my attack speed. I can't believe it's just because I don't have any weapons buffing my attack speed. It actually looks like my animations are super slow. 
 
Has anyone else noticed this? Or is it really just because none of my daggers are buffing attack speed?

Does this happen on all platforms?

Yep,i got this,oddly enough at the very end of the game, was playing as a mage and it took a long ass time to cast spells and to use basic attacks.
I think its because i got the Thumbs Up effect (or whatever its called) and it stayed with me even when Isabella wasn't in the party.

Already a thread on this here:

I also provided the answer.

Nope, not yet. Though they are aware of it, so it'll probably be patched in the next title update. It happens when you're friends with Isabela so you get her bonus, save while on a mission and then remove her from your party. Every time you load that save your attack speed decreases by 5%. Sebastien has the same thing happen, but instead of attack speed that decreases it's damage resistance. Shitty bug, but they'll iron it out. "

I found a fix for the X360 version!  Just follow this guys post to fix the problem. It worked for me.
