It is not a bug, it is a feature. Your AI allies want to protect you from harm and throw themselves into enemy fire. It is your fault if you want to snipe the enemy with your longarm!

Wwtf are you talking about, who say anything about long arm, and no it is not a feature, if it is then it must be the most useless and retarded feature I have ever seen .  

You are right; and I apologize for being sarcastic. The bots have a varying ability and responsiveness. As I do not spend much money (something like a  Euro per month) the bots behave differently depending on your win- or lose streak. And they are very bad at interacting with Mech special abilities, like Panthers Stasis Wall, Cheetah Mines, etc. 

Also, if an AI has an MD on the field, this activates only if it needs to heal itself.
