My Undead Mage is level 71 so I've made it to Northrend which is exciting and at the same time daunting because I'd just hit 70 a few days after WoTLK came out. Mind you I have a 70 Gnome Warlock that I abandoned so hitting 70 on a PVP server horde side was a major pain in the ass. Okay, WoTLK, it's a nice change of scenery but to be honest Blizzard tends to make simple things more difficult just because they can. For instance, Borean Tundra (whatever that city is called) is a huge pain to maneuver which I suppose is true of any city on WoW (Thunder Bluff anyone?!) so I find that element very annoying.
Lily I have 10 toons on Frostmane because I need variety and for some reason I like playing the lower levels
. I still haven't fallen in love with Outlands the way some people do, but I do find going through the portal really dang exciting, but once I'm on the other side I groan. Are you with a group in SM? Or are you trying to solo? Are you doing Cathedral? Have to have good crowd control when actually in the Cathedral or else death is eminent.
