Thief %/s (KMS Unlimited and GMS Tempest)

It ought to be Dual Blade due to Fatal Venom. With max crit rate, Ultimate Drive and Rapid Fire (both have the same hits/s) are better than Phantom Blow alone, but Fatal Venom makes DBs pull ahead. With ME and UD, no ToC, I'm getting 17.6/s with buffs and Judgement, so that shouldn't be enough to catch up, especially if you consider the practicality of using ME.

Thanks for the confirmation.
Just a hit/min game once everyone hits max.

Glad DB's come out on top, but will still be switching over to phantom regardless.
