Osbuddy never,
Osbuddy has high cpu usage and sometimes can lead to lag,
anyone who uses it when pking is retarded no offence to people who posted it,
Only use osbuddy if you are skilling or pvming,
I recommend rune loader, for one b0aty uses it, for a second from my own experience it's a great client for pking, no lag , no delay or anything when your hybriding it's perfect.
I'm a nher / hybrid so that where my opinion coming from when you click on osbuddy there always a small delay (even though I have a great pc)
but tbh fuck rs pking,
I per fair private server even tho I have maxed pure and zerk on 07
