Alhtough I am not completely against access quest but as I play on a pvp server they are almost impossible to complete with large guilds camping all the choke points (which makes for great pvp, but not so great for getting into the zones) and that means most of the content will be unavailable to small guilds and those that solo. The other item as has already been stated is lag and a lack of quest mobs and even in a large zone completing the quests are far more difficult for soloist and small guilds.
On a brighter note: on a pvp server we can kill those who wish to take our mobs and pvp will be stupendous!
PVP: 10
Gaining access: 0
