I am all for removing Void Form.
If Blizz can flat out remove Maelstrom from Enhancement Shaman’s and go back to more cool down dependent class, then I don’t see how they can’t remove Insanity from Shadow Priests and bring back shadow orbs.
Working on leveling an Enhancement Shaman now, in bfa, and the game play is a lot smoother than my main, max level, Shadow priest.
I hope we hear something soon about new changes coming for priest or at least they are listening. (even though clearly they are not since we have been bring up issues for multiple expansions now but I want to stay positive.)
