I don't have a DRK.
Anyways, so you're saying a DRK has to be 'working his drains' for 5 minutes straight to 'keep up' with the drain amount that the BLU can do in .01 seconds?
And..we're talking about the DRK that has been draining his whole life yet he couldn't find some sort of way to be better at it.
Blue gets Drain-ga via Blood Saber as well.
DRK can Drain-Attri but BLU got Osmosis as well.
But what I'm trying to discuss is the argument of utility.
Would you rather receive a lump sum of 50,000 dollars, or be paid monthly to reach the same amount?
Sure, you could reduce the delay in which you receive your monthly payments with your fast cast gear and what not, but it will never be that one fat 50,000 paycheck.
It is true with what you said about BLU, if they use Bloodrake, they can't use the other UL spells. However UL spells are pretty situational, and the situation I'm talking about is Drain healing.
Bloodrake can also be skillchained to Darkness, and it also uses a TP modifier that modifies its damage. Used with CA you can pushed well over 900, haven't tried using Efflux with it as I believed I would of over-drained my maxHP.
God knows how much damage/HP you'd get with Azure Lore in effect.
Going off topic.
If DRKs think that DRK can drain just fine as is, then that's that I guess.
I just happened to ask myself "Why am I draining harder than a DRK?"
