I've always used wd to push but it's kind of broken atm. Some skills don't work effectively and some not at all. It's still able to push pretty high (high 70s, maybe 80) but definitely not as well as it used to and with wiz able to push so much further and easier this season, people have moved in that direction.
It's pretty much the same as last season gargs but helltooth instead of LoN with zombie dogs leeching beasts -- can also use zunni+fetish if you want but helltooth works better. You want to push the min pack size up (8-12) and like 25-35 radius. One of the main problems is spirit walk doesn't work right so you'll get stuck on mobs and die probably. Normally wd sprints up and drops all def spells and tanks while gargs go to work. It kinda works that way now but not consistently enough and until it's fixed I would just focus on other classes. DH is a fun choice, doesn't come into meta very often and it's pretty strong.
