Has the visual effect of snow storm been changed?

Last night a friend and I were running a duo for the first time in a couple of weeks and mine was a lvl 41 Dual Pistols char that had picked up snow storm from the Cold Mastery epic set. Now the visual effect on the target seemed the same but the glow on the enemies that he inffected was enormous. To the point that my friend who was a tank literally could not see a thing while in the middle of a mob when snow storm was running. Even standing at the edge of the mob, which i did, meant almost total white out.

I've had this power before and certainly do not remember so much fog being generated. Is this new or have we both just never noticed how much there was before. And if it is new can it be changed back because not only is it distracting it was dangerous for me as the tank couldn't see any bad guys who peeled off to attack me.

Thanks for that Schismatrix. I didn't post this in the bugs section in case it wasn't one. I'll do so now.

Cheers.

The roboteching missles fired by the Malta robots are also creating a huge critical lag-inducing cloud around targets. I know they've always created a dark cloud but now it seems bigger and has a habit of totally blocking everything to the point that you have to zoom out.
