Hello, I mistakenly posted on battle dot net section of the forum, about the same request :
"Before Ahn’Qiraj launches, players in SoD phase 6 are enjoying the new content available, which is located in Silithus.
Contrary to other phases (except nightmare incursions), this content isn’t gated behind small events across the day nor is it gated behind daily activities.
Players then need to play for an extended period of time following very long reputation, quest and item grinds to advance to a couple of rewards from Cenarion Circle and Brood of Nozdormu.
Unlike nightmare incursions where you could play in multiple areas and do dungeons, this takes place in a much smaller combined area named Silithus.
This has become an issue due to the whole lvl 60 population on a server playing on this area, people take a very long time to do anything and they need to do a lot.
Layering could be an answer to this, but it appears that the number of layers doesn’t account for overcrowded areas.
For instance, you could have more than 250 players on 1 zone (Silithus), but the whole server still has 1 layer according to Nova World Buffs.
I would request adjustments so that players don’t find themselves competing against 2 other players for each mob tag, for the next couple of weeks."
