The only one of these that I could really see happening would be the Doriad suggestion. Otherwise, I genuinely think the raid cannon is fine as is.

As for Grimalkin, I think they need their own version of Instinct, rather than just getting the Felidae Instinct. Just tossing them another race's racial is a bad plan, as it kind of... kills the whole idea of it being a racial.
