Ghostcrawler mentioned during the Q&A that they're considering adding a no cd nuke for Spriests. I didn't hear anything else about it so keep your fingers crossed, spriests!

This sounds interesting, but wouldn't it make Mind Flay useless?

@Jack Spicer

Not necessarily. In order to keep Mind flay useful they could do a couple different things with the no cd nuke, for example, while it might not have a cd, they could make the nuke be conditional use, like overpower/revenge. Or they could make it so that it consumes your DoTs off the target like Envenom, so it would probably be best to wait until your DoTs were about to expire anyways, Mind Flay in the mean time, then nuke.

Those are the only 2 examples I can think of, but I'm sure they could come up with something to keep our button mashing dynamic. :P

Honestly we already have a no-CD nuke, the new DvP. You can spam that as fast as the GCD, it just isn't very mana-efficient and doesn't outperform a partial rotation. There's more than enough room to engineer a nuke. While it would be nice, I would much rather some of the basic SPriest gameplay see some tuning rather than get these band-aids (Dispersion, Mind Sear...)... although I guess any attention beats none.
