what the hell, girders limited?

pr wtf?
I know that t17 can be a pain when ppl keep blocking you all the time, but unlimited girders is the only thing that kinda ballances the game when you get raped by crates (or opponent gets lucky, whatever you wanna call it). FB wanted to limit the girders once, afaik it didn't work out...
About wxw, i see that shotgun has crate probability set to 246 when other weps have 1 or 3?

I guess axe and minigun are those lucky weapons that you talk about and therefore you removed them, fine - but why there's no homing missile?
