While snapshotting would be fine to get back, I don't think it's the main thing making Warlocks boring atm. Fear needs to not be trash, Curses need to exist, Soul Swap, SB: Haunt, and Dark Soul need to go.
Specs need identity--Destruction had much more character in the past. Now, all you're doing is basically swapping a couple of damage buttons around, that's it. There's no amazing: "OMG SHADOWFURY IS SO GOOD I NEED TO GO DESTRO" anymore. It's just: "Would I rather cast Haunt or Chaos Bolt?" "Do I want purple resource, or orange resource?"
I based my opinion on what I saw, and I posted accordingly - dude was genuinely trolling on stream, anyone who didn't notice that is a spastic moron without social skills. I have no need to pry my nose into every social outlet in WoW community. Stop getting upset Belieber :*
