Also, void zones on KT are bugged, and they are tiny and virtually impossible to see under your player model.
Yay for unnecessary and unannounced changes?
All flaming, trolling, and unnecessary categorization aside, I'm thinking a lot of background changes were made in this latest patch, in preparation for Cataclysm. As a side effect, a lot of things seem to have broken...
This week and last week, I was a part of a raid working on Algalon 10-man.
Last week, I had only a few problems seeing where the Cosmic Smash was going to land (little red spinning void zone, just like on KT). Only occasionally did legitimate graphical errors cause the effect to be harder-than-normal to see.
This week, they were flat out invisible 50% of the time, at least. Of the ones that WERE actually visible, I would only catch glimpses of red as I moved or set my camera to a particular angle. Or i would only see a split second of the graphic's placement effect, and then it would vanish. Ironically, sometimes I'd only see it AFTER it had exploded.
Nothing has changed on my end between now and then in terms of settings, addons, drivers, ANYTHING. It got to the point where we had to tell all the members of the raid to move to an unoccupied spot, rather than worrying about looking for it.
After reviewing the Frapses i took, there was at least one that was entirely invisible under my feet until AFTER I moved, at which point I only caught a glimpse of red. Had I not bothered moving, I'd have been dead with absolutely no visual warning.
Raid members were all reporting the same thing - very sporadic visibility.
