how is the pve questing? is it annoying?
like say....compare it with outlands being the good and stranglethrone being the bad.
It is actually really dependent on population that is questing in the area. If the population is good, then you wind up doing "public quests" a lot while you are PvEing, which are basically group quests where instead of having to form a group everyone in the quest area participates in completing quest objectives. This works out really well and the impromptu quest system without the annoyances of grouping is super cool. All of the quests that you get from the acutal quest NPCs are soloable and compare very favorably to the questing in WoW's The Burning Crusade zones. Once you do enough public quest stuff you get a reputation-like reward (generally doesn't take more than 45 minutes tops of PQ'ing to get max influence for the quest hub you are at).
While you quest you can also be in a RvR scenario (which is an instanced battleground) queue, and when the queue pops you can move your character to a safe spot near the camp you are questing at, enter the scenario, get some PvP done, and when the scenario completes (for which you get a healthy amount of XP and Reknown points, win or lose), you are right back to where you entered the BG ready to finish your PvE quest.
There are some other nice things about the PvE here-there is no harsh bring-a-friend code when pulling mobs, so if you just need one type of mob from the camp you can cherrypick it out. There is zero downtime for all classes-no eating or drinking-between pulls due to the crazy out of combat region and action point system. The game marks on your map the locations of the mobs, NPCs, or items you need for the quest, so you never really have to alt-tab to wowhead/thottbot to find out how to finish a quest. All classes are really strong in PvE, kill fast, and most have no problems taking on three mobs at once at their level if you get roaming adds while you are fighting or what not.
