1. The best and fastest way to play PotD is just... run through. At 99/99 on floor 51-60, no traps are dangerous enough to warrant being cautious. Besides, if you did play PotD enough... you would know that just staying on the outside edges of a room skips all traps since traps don't spawn on the outer edges 99.9% of the time.

2. As for PotD being better for DPS. No. Just no.
The math has proven it is flat out wrong. Not only that, but waiting for your queue gives you a break (the queue) and nets more exp than just banging your head against PotD repeatedly. Watch a youtube video, paint your nails, do some crafting while you wait - it's more rewarding than hitting 1 over and over.
