Melee Gun Thrashing

Not sure if you did this already but you could try to bind the targeting to the gun heat. The closer it comes to zero gun heat the less it changes the once found target/area. But i guess if your gun shoots 'blind' you have to weight the new (maybe better target) to the couple of turns you might loose. Because especially in the beginning of the battle 'trashing' is not that bad if your radar detects an enemy that is sneaking up to you (in this case i wouldn't call it trashing - its more likely an emergency reaction). Overall i would guess your targeting is a little to picky dependent on your movement and battle state. Its like 'oh this one is nice ... no wait this one ... oh hang on, this one looks nice ... hello what are you doing right behind me?' :) So i guess you can just let the targeting more space (dependent how many opponents left) to pick a target/area and should be fine.
