I decided to duel-box after one of my closest friends who I always played wow with and we raf'd each other, decided he didn't want to be my friend anymore. So that left me with pretty much noone to play with. I grabbed the $30 upgrade to MOP that blizzard was offering a week ago, and it took me about 1 night of lots of research, and trial and error, but once I finally got everything working and found what worked for me, it turned out to be really fun, I did 2 elemental shamans, and my dps is through the roof, my strategy is just to take all of the passive talents since I am a beginner but it's working really well. the queues for 2 dps were surprisingly short, maybe I got lucky.
I'm very tempted to get a 3rd account, my computer could handle it fine. I'm just really scared to try out a melee class(rogues,warrior,priest are only classes I havn't made), for starters I'm playing with an xbox 360 controller, so getting everything to work properly is already a pain.
I'm really enjoying what I've been able to do with just these 2 shaman so far, it's really fun. hopefully it only gets better!
