>>13423231I don't remember Heero accomplishing much while in the Heavyarms, he was on the run the entire time until the sabre duel part where he fought on par but then started losing again. I'm pretty sure the Tallgeese never got grazed.
Duo's specialty has always been melee, besides a BFG is an impersonal weapon for someone who calls himself a death god (the idea being that he usually takes the lives of his victims personally, i.e., getting up close with the scythe).
Quatre never preached any kind of pacifism when it came to fighting OZ.
The only reason Trowa ever resorts to melee is that he spent the first 3/4ths of the battle shooting everything up. When he ran out of ammo in Endless Waltz, he didn't start beating down anything or trying to tank enemy fire at all, he just backs off.
