I leveled my rogue to max at the end of cata (like hit 85 with three weeks left) and told used its be my main in MoP. That didn't happen but I just finally hit 90 and I'm liking it a lot. It's really a fun class all around and I like the idea of rogue, just the concept is pretty awesome.
I'd play one if I were you. I'm on my phone but I think the other option was Mage? I'd pick rogue over Mage any day but all I play / have played is melee.
