They could make a new "slayer pet" and you could maybe buy tickets from Nieve and gamble them to get the pet which would be extremely rare. They could also add potions like antifires, super sets, restores, etc.
I don't really pk on this server because it's mostly a PvM server. But if you guys feel like it needs a slight buff to accommodate your risk, then I personally think it should be fair for all the game modes except for Ironmans/HCIM since they can't pickup any of the stuff you drop/pk.
For port Phasmatys, simply teleport to experiments from the teleporting wizard and go up the ladder. You will be a few steps away from the farming patches.
Support for the grimy herbs and i personally think they should add a quest that rewards you those secateurs. And i'd give them bonus exp when worn instead of yield since you always get around 10-12 herbs per patch.
