I mained a rogue in vanilla, so I naturally made 2 druids waaay back in the day to do stealth runs. Worked really well with 1 being resto and 1 being a bear tank. Was able to stealth snipe mobs in LBRS / BRD / etc... as well as stealth mine/herb.

As far as using a rogue in classic, if you aren't planning on maining it I'd consider shaman or warrior in that slot... Don't have to deal with combo points etc.
