Mountdoomskull run with:
LBMA, full Luck, Chaorrupter + AFDL piece and Spiral Carve.
LBMA is a little hit and miss, it's not always easy to keep your hp low and still stay alive when you aggro 2-3 fatties at a time, which can crit for up to 500 on LBMA btw. At about 25% hp, it was possible to 1 shot anything with Dimished Steel, which could skyrocket the completion speed of certain screens, that plus a 5k crit with Dark Mantle and a 2k+ semi fast auto attack is bound to kill quickly.
Scarlet Sorceress, full Luck, Chaorrupter + AFDL piece and Spiral Carve.
Before the timer started, I stacked Crimson Ritual to 5, since you would be at that efficiency if you are farming for an extended period of time anyways, that maybe be 1 of the reasons my times are so much faster, another might be that you used Wiz instead of Luck, Luck does provide a higher damage output for Scarlet, so that's what I went with. It's also important to always target the weakest enemy when using Mirroring Arcane, since you will deal more damage to the big guys that way, even to the point of being able to 1 shot them.
LDK, full Luck, Chaorrupter + AFDL piece and Spiral Carve.
This doesn't surprise me too much, LDK (for as much as I don't like the skillset) does great single target damage, so you can take down the fatties pretty quickly for the most part, something that I feel a lot of true AoE classes lack. Low cooldown skills with somewhat stable damage output, a budget VHL.
I feel like using Awe Enhancements are fair enough too use, sure, it makes these sorts of tests more unreliable, but as long as you do 3+ tests for everything, it should even out for the most part. If it was a test about how fast you could kill a single enemy, Awe enhancements should always be taken with a grain of salt, but because both mems and non mems have access to the same level Awe enhancements, at least fom 70 and up, it doesn't exclude non mems from being "competitive" and giving accurate results for a mem as well as a non mem. It's not like you would not want to use Awe enhancements when using a class, unless you are going for exact numbers, or just don't feel like using them, for one reason or another.
the use of spiral carve heavily affects the speed of clears since the chance to proc it is not 100% consistent
AQW will always have random elements that affects combat, insane difference between critting and not critting, Awe enhancements, mana regen (from crits, from dodges etc.) which are out of your control. Without using Awe enhancements, you are testing in an unrealistic setting.
I feel the purpose of the test is just to give a general idea of how good classes are at dealing with a lot of enemies while still being able to survive a decent pummeling, not to crown king and queen of farming.
