If I’m looking at BiS right for Warrior then you’re only looking at 4 or 5 items from Naxx including KT weapons, Armor you’d probably be wearing rank set. Unless you want the full tank set.
Personally, I would lean closer to rogue. There’s too many pros/cons for each but I think as a Rogue you’re less vulnerable solo while still working well in a group. If you have a crew to regularly run with Warrior is probably more fun.
