With BlastX finally doing colour variants for knives, could we get an update giving all the previous knives the same variants as the rests of their sets to match?

I have 5 or more recent match in deathmatch was with 5 or more AFK-boys, they kill some guys to have stats, maybe it's ok, but it's pretty suspiciously. Upd: that's guys was not same P.s. sorry if my English is poorly, im from Rus :P
