Right, but while I'm probably going Demo PvE, I'm not sure I like the feel of it in PvP. I'm also a filthy casual when it comes to PvP that isn't playing anywhere near 2200+ rating, so my opponents aren't always as expertly on the ball about coordinated pet killing.
I can see the appeal of SB:H for putting pressure on an enemy team in rated PvP. But half my consideration is for more random mucking around in Ashran, where unexpected 1v1 encounters are a thing that's going to happen. Under those circumstances I keep coming back to a powerful pet with a root being an attractive choice.
