I think servitude will need work, especially the Abyssal. I hope if they buff the demons, that they put that increase into the talent itself. I absolutely do NOT want to go back to Cata days were the Doomguard was doing insane numbers. So boring.
I also would like it if Chaos Wave became worthwhile to cast. Did anyone test on beta how HoG weaving works? Same as live still? And on that note, (maybe this got answered in a tweet months ago and I forget) is Doom snapshotting Meta? Either way I still think they should change Doom to be 6 ticks over 60 seconds (1 per 10) so that it can benefit from 10s procs.
