this is a small one but i would love skill styles for staves with one good example would be to make a style that makes inferno and ice staves shoot green balls of energy and make the lightning stave shoot a green beam just like fatecarver. Another could be fore nightblade making it so your inferno and ice staves shoot red blood orbs while the lightning stave shoots red energy. And one last 2 example would be a necromancer style that makes the fire the necromancer flame blue while the sorc could get one that makes the ice stave shoot dark crystals.
all in all, i love the concept of using the new skill styles to help aid RP in a new and fun way like this to really encourage people to make rp builds over just making pure power gamer builds
