I think personaly dark ,fairy, grass, steel, dragon, psyhic, electric, ice, bug ,ground, rock,
would deserve better abilities and gimmicks in future... some like queenly majesty(rock/ghost bastet cat god) or dazzling would be cool to see on other pokemon more too.

Seriously some like poison maybe could get a gimmick that unites two abilities or more? grass, water, psychic and fairy
its own substitute ability? generaly protective abilities are rare, maybe too rare in comparision to the offernsive and power boosting ones.
