Hello there, what happens to me is that if I farm place which is heavily farmed. My bot will go and use instant on one of the mobs, but since it is heavily farmed.. some people tag the mob before me and bot still goes all out against that mob, wasting time and efficiency, also giving others time to tag other mobs, while helping the enemy. Heh. 

Well is there a way for bot to recognise whether I have tagged the mob? And if not leave it...

At the moment I am botting on tbc

Try looking in the advanced settings, uncheck "Can attack units already in combat."

Sometimes I've seen the bot use an instant attack but someone else got the tag just before you, but since the cast went off, it is in combat so it will not ignore it.

That is the exact issue... Of course I looked into settings. I was wondering ehether this could be fixed somehow since it has really bot like behaviour.
