The biggest issue with the class right now is pet AI, and more specifically the base egis. For years the pet AI design that SE has implemented has been embarrassing to say the least, and the job changes this expansion have really highlighted just how bad it is. At this point, I'd rather the base Egis just be removed entirely, or used only for visuals in game. As much as it may not make sense from a theme perspective (and would probably spark outrage from some players), I just don't think it's appropriate to keep this pet system in place if SE is still refusing to fix the long list of problems it has (some of which can be traced back to the HW era).

Aside from that, the 5.1 changes have mostly fixed the mechanical issues the job had.
