the root arrow needs to have its duration halved.
hunters need all knockbacks and movement forcing abilities removed.
turtle shell needs to either be poppable or reduce your damage output by 99% while active.
stuff like snipershot which can 1 shot players should share a CD with all other hunters in the match, or alternatively put this on a talent row where it competes with turtleshell. high damage output should make a hunter the most fragile glass cannon, not a highly mobile tank.
