Why should something that only reduces the amount of RNG in the loadout system be so hard to obtain? Safe to assume there will be other ways to receive and/or purchase weapon kits in the future so why add them into the game like this??
Even as a guaranteed level up reward they would still be too rare for their actual value IMO. Not trying to be super negative, just seems like a missed opportunity to create excitement for a feature that is a welcome (not essential) addition to the game.
