You can't be serious. Autofire is less or equal accurate than barrage, that is why you have a barrage option, not just attack ground.
Do a test with these two units first, thank you.
I am pissed because in COH2 these two guys barrage are actually different and relatively inaccurate, you are NOT rewarding by manually barrage the target.
Pack Howie barrage just shoot 3 or 4 so-call anti-tank round basically does nothing, and have a long cooldown. If you leave it auto-fire, it is just shooting non-stop.
Same logic for the LeIG, the difference only the cool-down isn't that stupid long, just auto-fire still WTFBBQPwn.
