People talking about the old days, did you even play shadow? It's practically the same as it is now other than the fact you enter void form occasionally. Still gotta maintain the same dots, still gotta clip mindflay, still gotta press mindblast.
In-fact the old shadow was so retarded you could make a macro to do the entire rotation and press one button the whole fight and you want that back, to improve a lack of burst and aoe?
What planet are you on. Shadow priest was a meme for a long time, there is even a video of tom cruise edited to rip the piss out of Shadow.
Shadow suffers from the same problems it always has, it also excels in the same places it did before, with some minor improvements to gameplay. If you can't play it well, you just suck but you have to accept you won't out AoE anyone without sufficient time.
No one in their right mind wants shadow orbs or mind spike spam to come back.
