Cor is pretty god-tier in Voidwatch, so I can't really complain. It has a ton of procs, a Regain roll, and the ability to damage from a distance. I don't expect to use it in Abyssea much, but Wildfire Brew definitely has its perks. Overall, I don't think they really have that much to "fix" with Corsair right now. The 11 buff and the addition of a third active roll are amazing, and Voidwatch has crafted a true niche for Corsair that has never really existed in previous content.
