Bowazons are good, if you can get your hands on mavs then you'll be smashing the early content esp as you can off-screen kill a lot of stuff.

Any sort of summoner isn't bad, as early game you struggle to get those maxi res so having a wall between yourself and the enemy helps a lot.

WC Barb is very good as -magic res is pretty easy to get early on (laz gloves, shrieking, echoes etc.), you get your BO, passive MF and it aoe stuns which again helps a lot with those early game squishy struggles.

6.0 is bringing a lot of unknown changes though, so who knows what'll end up being the go to route!
