When there is a group of enemies surrounding a "captain bot", and I run up to lock-on to one of the player controlled enemies, 90% of the time it will lock onto the "captain bot".
Please just disable them as "lock on" characters. It is so annoying, and when I do want to fight them I rarely lock on.
They are essentially Chinese water torture, except at least with that I get some hydration...
I understand part of the strategy is to fight near the Captains so that they can help you get kills or distract the enemy players, but for some reason they seem to take "lock-on" precedent - even if they are not the closest enemy or the one with the clearest line of sight.
I could be looking at an enemy player with about 3 feet of distance between us and it will lock on to the captain 10 feet away and behind me.
