Hey I have been thinking about tha for a while so I will write it down so arena might do something about that.
It would be really awesome if we could costumize look of engi´s kits. Becose it is really nice to have cool looking pistol or rifle but as I play engi I use kits like 80% of all time and it this have this one boooooring skin. With only one weapon slot I think that engi is missing some kind of kits customization option.
