When I read the title, i was thinking druid. The druid as a caster will do much better at higher level (moonkin) druids are best at feral at the early levels. I think the best class for a rogue is any of the hybrid classes. My first character was a paladin, and anytime I played a non healing class, I hated it. A Shaman might help u too, should be pretty easy to macro in some totem drops, and a couple of dps buttons. A paladin wouldn't hurt, they can take a few more hits than the other hybrids, is easy to macro healing, are the best single target healers, and have useful buffs.

I think in the long run, the druid will be a godsend. You can both stealth around to avoid ganking, or to cause it, stealth instance runs are possible, and the druid can heal and rez when necessary (maybe get engineering on both for jumper cables)
