Just like we have for armour, i'd love to see skins being able to go onto guns, just to give a bit of customisation. Along with this, i reckon an aesthetic slot for armour, like being able to add smoke effects, spikes, feathers etc (if that's your style). The skins would be like the ones in Micah Bell's vid. HE designed these ones and they look great, but if there were heaps of unlockable skins that would be great. Hopefully this will come in House of Wolves :)
