What feats do you hope to see in Xanathar's?

[Naanomi]

Oddly, no one has mentioned that we have basically zero caster feats. We have elemental adept, spell sniper, and warcaster. None of these feel like they have quite the impact on a pure caster as the martial feats have on the martials.

Probably in part because only the most purely martial classes get bonus feats (Barbarian aside, who tends to benefit from boosting CON more than other classes)
