I managed to hit level 120 on my first character on my third server today. Destruction warlock. It's probably my least favorite warlock spec to level this expansion, but even with that, it was still totally fine. I've got a survival hunter that I'm leveling with a friend that's about halfway through, sitting at level 115. I've also started my third demon hunter through the process, but he's still fairly early on.
I may shift back to alliance for the fourth toon on this server and do another frost DK.
Happened upon the mysterious flying fish of Zuldazar today while finishing up the warlock.
All of it's buddies were clearly down below in the river, so I sort of felt bad for this guy. Must be kind of lonely just hanging out there in mid air.
