i never liked hunters for pk but as a ranger in general you'd want to levelsit at 35 (where you get wildfam) and 40 (where you get snare and still not in range of hero chars).

At 35 and with the right combo (half-elf good hunter is not it) you should be a powerhouse and pretty much able to destroy everyone in your range. Almost the same for 40 with snare and change of tactics/more careful play albeit with less victims that you completely dominate.
