Suggestion: Random finisher, level-up, and skill effects.

Hell, allow for a "randomize" option for ALL mtx slots as long as it makes sense for the slot it's applied to.

Doesn't have to roll a dice per use of a skill, but maybe randomize it every map/instance the player loads into.

Given how the latest hotfix limits the number of level-up effects active at any given moment to one, as well as how many MTXs people may have stocked up over time, I think a random option for pretty much all mtx slots would be fun.
