Which is better for pve/farming mage or rogue?

[Lolifee]

Mage has pretty insane aoe esp with rusk gun. Rog is lacking that.
With a good loadout they do near equal damage at bosses.
With rog ulti u can take down bosses asap while mage ulti can absolutely nuke aoe wise
Tank can do anything and is hands down the best class.

Rogs lack survivability, while mage and tank have invulnerability skills.
