As good as the idea sounds thematically, it'd really cause a lot of issues IMO. RNG mechanics tend to be unfun in RP games, as evidenced by how much people hate evade builds. Not to mention, testing becomes a bit more of a pain because things that are problematic can be chalked up to 'oh, bad RNG' a number of times before people even register that there's a problem that needs to be sniffed out.
