I haven't really seen anything about it yet other than the hero talents, and I don't usually speculate about it too much till the betas out and things are more set in stone.

I played to around 27 this season, it's really good at killing healers specifically pres, rdru, rsham and hpal. So against those teams try to set up swaps on them as much as possible whenever you've got a stun. You don't have to start with hoj, sometimes it's better for the dh to use his stun and you hoj off since it can be hard getting close enough to stun them yourself sometimes.

Just look up people at a similar rating to you on check pvp, and message them. That's honestly the best way and how I found the guys I'm pushing r1 with this season.

When you have pet stun it's usually pet stun into trap, but when you don't have pet stun you try to hoj to set it up, but if their playing too hard away from you, you can also just scatter trap with hoj on kill target. If you hoj healer you can have druid bash kill target too for cross. Druid getting cyclones is really important into most teams, so if they can try and land it off the stun trap go it's really strong, but even when they can't just cloning dps low to to peel is really important too.
