Way to equalize Android and iOS Legend runs...
I don't know how easy this would be to implement, but it seems the obvious way to equalize things would be to only count time spent in fights. They could put a little timer in one of the corners which only runs during fights and shows your cumulative time between heroic and master. This would also mean that a legend run would not necessarily need to be done all at once, so you could wait for energy to refresh rather than buying a ton of energy refills. Of course this means that Kabam will never do it and continue to unfairly favor iOS users...
