You can only fire at 1 target because ur guns dont turn to face the enemy but ur upper boddy does  how ever u can RR/Ewar/transfer diffrent targets at the same time

But I thought EWAR etc goes in the mid-body slots and that's where the guns are at too? Surely there must be another reason, right now, you could pretty much replace the multiple guns with one gun with a 4x 5x whatever damage multiplier.... other than reducing your own damage, I see no use.

I can see how you might see that the target is about to explode and so you turn off a couple of guns, but in the heat of the battle, would you care more about an extra round of ammo, or being the last one standing? I would suspect the latter, and so players will tend to fire all guns possible except in extremely weird situations (like tagging spawns, though again it comes down to saving ammo).

It is weird, how the setup restricts you to firing at only one target at a time - seems to be no logic. Surely the bots have figured out that if you have four guns you need to place on a body, you can place them so they are free to move on a rotating wheel so they can fire in a 360 degree circle. Come now, they are sentient!
