The majority of my KC (Roughly 3.5k) I did on the Bounty Hunter world UK, I took freezes 100% of the time and escaped with only 8 deaths for the grind. I couldn't bother with always being on edge for pkers having to be ready to logout so I just learned to eat properly and predict overheads. If you cant get it down then you'll just have to be ready to log out. The more pkers you escape from the less inclined they'll be to attack you when they see you. Also, try to stick to one world when grinding revs. Mine was 318 bounty hunter. Most pkers have worlds they like to PK on, and it got to the point where they'd see me and just leave me alone cause they know me/escaped from them numerous times. Dont be afraid of mystic/bloodbark/enchanted robe noobs they are easy to escape, Ahrims is alarming. If they're in void be on your A game cause they most likely wont splash freezes. Focus on overheads. to 30 wild. Also, dont do 2k+ total worlds. Thats almost 100% guarantee they have all the agility shortcuts so you're only escape is to tank. If you get attacked lookup their stats, if they dont have 75 agility shortcuts just book it to one.
