What if the Enhancers we used in the game had an element of randomness to them when they dropped?
So like, imagine something like the old CoX Training/Double/Single Enhancements, except that the Trainings always give you a totally predictable, and meager, stat bump to whatever stat they affect (i.e. +3% Damage, etc), then maybe the DO does that for two stats (so +5% Dam and +5% Range) but the SO, which buffs three things has variable numbers that are rolled for every time you get one. So this time you might get an SO that gives +10% Damage, +7% Range and +6% Endo Reduction, but the next one you get might give +8% Endo Redux, +8% Recharge Rate, and +9% Accuracy, ect.
Very Rares might have better numbers, or have some way that you, the user, could select that they do when you get them, making them a much-desired wildcard type deal.
