Im on the process of going through the campaign on a ranger at a8, with the wildspeaker wolves. Its just awesome. It's easily top 3 i've ever played, including second character twinks. High movement speed, absolutely trashing dmg, and huge clear. Dunno who came up with that first but check palsteron and use rain of arrows for attack and with ballista for easy, fun clear. go Manaforged arrows until first lab, switch before a3 boss if you got the the sockets (you only need to selfcast one) and enjoy doing 1-4 second bosses until forever, while running fast enough to cripple toaster comps.

On top of that its fairly simple to pivot to another build in maps, so just go ham and enjoy the ride! went and got the awoo pob https://pobb.in/4-G9c9NxhkXy
