WOW didn't get guild achievements until Cata.
If you read any patch notes, guild banks are coming. along with many more flashpoints, operations, warzones, dailies, and a new Companion. :-)
WOW is the same thing..............you start out in your level 1-5 zone, go to the next zone to level that is on par for your level, etc. You cannot go to a Cata zone at level 1 and do quests.
Low level PVP in WOW sucks too. You either wait 2 days for a queue, then go up against FOTM class with BOA gear and have 0 chance at doing anything. Low level PVP is pretty good here.
