The fact is exploits will continue to be made until you guys finally make content itself worth running. A public event should drop 10 tokens, strikes should drop 20 or more. PvP matches should drop 15. If you want to max charecters you need a total of 1800 tokens. And even with that idea of buffs to tokens it would be more then 90 strikes in a week. Not exactly normal gametime for the average player. At the current drop rates though it's much better to grind running back and forth between loading zones or shooting nests.
