I like Hildy, and his content from the last patch was a step-up from how it started. That said so long as we get atleast one new good long running side-quest storyline in 4.0 I could do without him.

THAT SAID...I do agree that removing trials from 3.x Hildy was part of the problem as those were some of the better parts of 2.x Hildy. Also no Gilgamesh. Course I would be fine with just having more Gilgamesh in general even without Hildy but he works good there.
