No... There are multiple good working RS3 bots, aswell as OSRS bots, so why would botting be dead?
Yes, Jagex is getting better in detecting bots.. They have too, but it's also a matter of how smart the botter is.
You could look into AHK, Pulover or WinAutomation.
But, they will never be the same as a true botclient, and they are easy to detect if not done correctly.
I got used to bot on EoC and play legit in Legacy ;P it just feels like the bots work better on EoC
XP 4 Prayer dropped back to 40-50k :p so its kinda the same ;p
