Most fun thief build?

I read a lot of very fun thief builds to play. I never playd a thief before, and i think about to level one. Do you have any suggestions for me(With build-link pls <: ) Is it worth it to push him directly to 80 for Celestial Armor or just use the lvlup-Scrolls and get Berserk or whatever stuff?

Edit: Will start in Open World. Maybe fractals later, but not really my focus.
