Anyone who walked around the zones in 1.0 could see all the copy and paste, and how all the landscapes looks the same. Most apparent in Thanlan. The hills were the exact same at each spot. I didnt encounter the invisible mobs that much though. But I always noticed players vanishing and reappearing at the zone line. Or the annoyance of having to go to town center in Uldah to hear the shouts.

I dont get why anyone would like these things.

THe Aplha videos already show the variety in the zones in the Black Shroud. What is there not to like?
Invisible zones that require copy and paste, and vanishing pcs and mobs.... or a visible zone where they landscape in every zone is better.... no contest.
