Dark Devices - Exploitation

[Umbrah]

The FATE event Dark Devices is being used to effectively power level players by intentionally avoiding completing the objective and farming the endlessly spawning monsters that are not relevant to the completion of the FATE.

This whole argument/exploit claim is ridiculous.
You're running FATE's for exp... They are getting exp...

ALL FATES HAVE TIMERS!
So just help them, which will help you, and before the timer clicks beat boss.
Thus maximizing your exp (which is what you're trying to do isn't it?)
