Level 71 with both my 70s here.
And been there for quite a while.
Quite frankly, I haven't had the time to level up my now 71s. Sure the quest are super easy to do. They just require doing a ton of them before you level. Which make sense since Blizzard didn't want people to speed through getting to 80 (though people have done it in 27 hours straight), but for someone who can't play WoW everyday (certainly not before my final on Wednesday. The final that will determine if I graduate or not. :help: ), it's just, a whole lot, A LOT of grinding.
And really, no one should be surprised about there being a ton of Death Knights in Outland. Heck, I have a Death Knight. I don't play any of them that much/at all (yes, I said them. I have 3 on 3 different servers. :lol: ) but I did it just to see how they are like. And enjoyed them enough that for the three servers I can have them, made one for each.
I'm still sticking to my 'mains' though.
The one thing I have been doing during my breaks of studying, was level up my bazillion alts. Yes, it's bad to be bazillion when you don't have the time. But at least with low level alts, I can earn extra gold by working on their profession, and then sell stuff to AH. Something I wish I knew when I started. One of my alts already has 25 gold, while being only level 20. I can't recall any of my 70s having that many at that level.
Oh, and with alts, at least they level a lot faster. So I can have the 'satisfaction' of 'going somewhere'. Even if it's simply from say, 14-15.
