Never used this thing, never will. But that's cause I've never raided before, bwahaha.
I think AVR can help those who are new to raiding (like me, when I finally do one day), but it's a shame it's being locked down. I can see the logic behind Blizzard's argument, but AVR doesn't really follow the same rules as other addons. I know they're going to block it and similar addons because it's interacting with the game world, but I mean, that's not a
real reason, is it..?
Edit: Also, just something quick, but I bet someone sooner or later would have used this to create awesome, 3D, pavement-art a la Julian Beever.
