Looks like they're shifting all the damage back into dots, which is good. I also like that Drain Life is once again the filler spell. But, there's no real mention of curses or fear changes, as well as no mention of SB: Haunt. It is an early preview though.
Also hoping that fear gets buffed/reverted in some way. It was extremely broken in MoP because of the ease of applying dots (SB:SS and SS no shard / cd). It didn't impact your damage as much then as it does now to cast fear. And when you do cast fear in WoD, it just breaks to a whiff of air. With lower DoT durations in Legion it's probably going to be even worse than it is now.
