keep working at it. the only people with 70's in this game that i know of is me, newf, and scorpian9x. also the last 11 levels in outland aren't bad AT ALL (the first time through) if you do quests. if you have a partner for most of it, you could actually call it fun. skip instances, do every quest you can get your hands on, TRY to do most of it with a partner, try to do every group quest you can(pretty fuckin good gear from the group quests avalible at the end of most chains), and yea, if you do quests, you won't need to grind mobs for levels, as you will still have quests left over after you hit 70. by that, i mean, you will still have quite a lot of quests left over after you hit 70, having only done quests to level from 60-70.
umm yea...why do i end up making a post about this game only to have it come out as ZOMG DECENTLY BIG WALL OF TEXT. i played too much of this game.
