I really hope someone is reading this thread, i have a grav kin and basically because grav lacks synergy with other troller sets and its difficult to use even for veteran players and I dont know about specifics of how it should be changed, but it definitely needs some love. the targeted aoe dimension shift idea is really good, the reason dimension shift sucks is because it lasts a very long time and the enemies trapped are unkillable, right now its only a solo power but it could be made useful for teaming and soloing.
