You can get some pretty incredible burst damage that will annihilate an EFC with some stacks, in addition to silence, psychic horror, mana burn, mind control, life grip, and just all around survivability. PWS, dispersion, PoM, and being able to toss some heals if needed is really nice. Double tap SWD below 25% is a lot of fun too. Try them out and see what you like. All three of those classes are viable choices, and can be very good in RBGs. See which one is the most fun for you and run with it.
Have you played with a good spriest or played one in RBGs that you can say they can't bring "game-changing skills", because they most certainly can and do.
