I haven't played runescape in forever besides botting on rs3, I was wondering if pking was still pretty populated as well as zerker pures. Always wanted to make one but never really took the time to make one and go for it.
osrs: certainly rs3: no pure is really viable anymore. It's so much more beneficial to just go full main.
If you're looking to pk in edge, zerker is probably the most enjoyable build for it. Hybriding community within zerkers is very small though.
Assuming you mean on osrs. 60 attack zerker is a pretty fun build, but voiders might give you trouble. You can of course go 75 too for whip/godswords if you are okay with the higher CB level.
