Memblur spells do work. I would say I have a ROUGHLY 50% success rate with Reoccuring Amnesia. With 4 25% chances that seems about right.

I stopped playing on live maybe around 2004 and the chances for a mez to memblur the target seemed to be very similar if not the same is it is here. I very often would get attacked after a warrior broke mez with a taunt and kick, very rarely if I had a Paly or SK using aggro spells.

Dersk, it sounds like you are being defensive in your responses.
Please understand that I am interested in this thread and trying to contribute information. I'm not saying that you are wrong, I'm just posting what I can to add to the discussion.

I know very well that trusting memory alone is not a very accurate method to research things and I also have no idea how spell mechanics have changed on Live over the years since I played there.

Is it possibly that the memory blur component checks on every tic of the mez? That would in theory add to the chance of a blur happening. Honestly I don't know.
