Exp players want accelerated dungeon mob kills per hour? The answer is simple.

Entice veterans to help. This creates a twofold benefit:

Queues are significantly shortened, dramatically reducing wait between dungeons.
Veterans know exactly what to kill and how to maximize kills per hour, because they WANT fast clears.
Even when they skip mobs, it is for efficiency, as what is skipped tends to add a great deal of time for little gain.

OP...this thing you want... will actually reduce your exp per hour, not improve it. Consider this, for the love of Pete. Your net gain for getting on the Zodiac gravy-train will not disappoint, if you give it a chance.
