I would think you'd have to gear up to some degree. Perhaps you could make some friends who might let you borrow gear if need be. But leves make decent money at level 30+. I think if you work on some leves you could get half-decent gear. :3

I'm unclear on the requirements for the new "final boss" battle. Unsure which quests need to be done first and such. Patch notes might say.
