Ves didn't feel like spending additional credits on additional virtual component licenses. One of the problems of the DarkSilver design was that it allocated the majority of its space on enhancing its active stealth systems. It contained precious little space for any other systems.
Most of the variants he'd seen took the FFL-25 and added alternate loadouts. Instead of a piddly little knife, the other mech designers mostly provided their variants with limited-use weapons that delivered a large amount of damage in an instant such as bombs or acid containers.
To be frank, Ves considered employing the same means, but he held off because he wouldn't add anything new to the game.
In addition, the solution seemed like a cheap cop-out that turned its back on the original intent of the DarkSilver line. The players who buy the variants mostly use them to sabotage the enemy base and supply depots instead of assassinating enemy mechs.
