I have experience from TBC and up till Dragon Soul in Cata, after DS I went casual and have been pugging mostly up till now.
Main problem for me is that i work a 2 shift, which involves rotating between an working hour of 07.00-15.00 and 14.50-22.00 every other week so I hope we can figure something out.
My most played role is rogue, but with the comming expansion I'm willing to reroll to something "new" (I'm an altoholic so got every class at 100 with ok gear)
