Melee SV is fine. If anything, they should just add the 1-2 spells back as talents in MM or give people the 4th RSV. I can guarantee you that it won’t age well and it won’t play like it did in your glory days of pre-BC. They can’t get SV or BM working right, and MM is shakey, do you think they can give you a balanced and fun RSV? Good luck with that.
Do we need buffs? Yes. Do we need better Torghast powers? Definitely. Do we need Dual Wield? I would like that very much, thank you. We haven’t been reworked since SL. Many people love SV, and it needs to stay around.
If you made it a dot class again, it won’t be like current Shadow Priest or Affliction. It won’t be fast dots, it’ll be slow Feral / Rogue dots. You can’t have a mobile ranged class that can do all damage on the run with big explosive fast DoTs.
I’ve argued enough with the RSVs like Beeps, and it’s tired. Keep marching the forums for a return to RSV, I wouldn’t hold my breath.
