My issue with this kind of randomness is that it reduces the skill depth of the game. Consider, for example, a variant where you could choose which crew member to send on a likely-suicidal mission. You'd have the same chance of somebody dying, but now there'd be a bigger incentive to have redundant crew. Or lacking that, you could choose which of your trained crewpeople, or what racial bonus, you least need.
FTL does do that, as when you make your choices during a certain scenario, such as the space station that has a fire. Normally you have the choice to go in and help, which will randomly let you know if you are successful or not. But, if you have a Rock crewmember, you get a blue choice that automatically succeeds, as the Rock crew are immune to fire. You can also get a blue choice if your ship has the correct equipment, such as a repair drone, improved sensors, or the correct weapon mounted.
Very fun game, you will tend to lose more often than you win, but that is part of the fun.
