There are some errors in the timeline:

Diremaul

Diremaul, a new dungeon for players level 56-60, is now open and ready for business. Diremaul is populated by a fierce tribe of ogres and is located in the western region of Feralas. Diremaul will be limited groups of no more than five players each.

Hi,

I've seen somewhere that the Staff is fully aware of these elements and the current timeline has been designed on purpose.

[Netherfrost]

And its very clever aswell. It adapts to the servers progression line depending on the server first clears, instead of a static 6 months etc

[Hatson]

PvP will be on release, because.. well, should be obvious. There are many people who only play for PvP. And that's all they care about. Making them wait 6 months or something would not be good for anyone.
Besides, the pre-buff stats on the pvp gear is far from best in-slot back then. They would not break the item balance. I mean, some of the old Rogue pvp stuff has str and parry on it.. There is better gear out there on initial release without having to grind any PvP.
