General

like the first poster said, if you 1-2 hit mobs with yellow aura.
and you still 1-2 hit with dark aura, yellow aura is just better to use over all since yellow aura can break speed cap and is jut smoother to use.

@shadowind7 dark aura 10% boss dmg is pratically useless at pretty much all important end game bosses since debuff aura gives you the bigger damage boost.
normaly the best way to go about it is use debuff, wait 2 secs to take effect on boss then switch to dark for more damage, buts its really a pain to do that every 8 secs.
so i usually stay in debuff aura to whole boss fight, sometime swtich to red depending on the boss i fight.

Would it kill faster though? The +2 speed increase is very noticeable, but I'm not sure if it is the same, worse, or better than hitting harder and slower.

Has EMS not recieved the revamp? We don't have "advanced" auras anymore.Personally, I love speed, but I think dark aura is still better once you get the +10% boss attack hyper.
There was a bunch of calculations someone did that was something along the lines of ~16% damage to 1 speed ratio.... I can't seem to find it.

I was wondering that for bosses myself. It seems that AYA works better for me.
Cause I do like 2.3mil per line with ADA and with AYA it's only ~2.1mil but I can definetly see that speed difference.
