If you want /that/ kind of warm and fuzzy feeling, join the IRC channel and look for Wilbur or Gurblash ;)

PvPWise 4locks + 1 priest is a pain in the ass...so many dots/dmg incoming + so many fears available + priest to dispel/heal anything you do to them + felguards/felpups effing you up etc...yea it's a good pvp group to go with. 5 locks might work too but having that healer helps if you can handle the micromanagement.

As for the Grind...2.3 made it sooooooooooooooooo much faster, quests give 10k exp each pretty quick + it's alot less exp per lvl to lvlup too, no more elites anywhere outside instances sans a few(like the alterac ogres in back aren't elite anymore for example), and all instances got turned down a couple lvls + retuned gear in some cases. While most people preach to screw collection quests, consider them instead. If the droprate is so bad after 40kills you get ONE drop for ONE char, screw it. If it takes maybe 10 at worst, 2-4 usually, to get 1 quest item drop, go ahead and do it; not only is it good quest exp + quest reward, it's time spent grinding without technically being grinding, as you have a goal and specific targets. The key is not to consider it pure grinding, because it's not :p
