Not exactly true in the case of Malk to spoils. Thok however, Huge wall compared to Malk.
We are currently wiping at about 10-15% on Malk with 200 wipes (2 kills) under our belts. Spoils we've been close several times with only 50 wipes(0 kills) so far. We just have a couple people that suck at avoiding orbs going into a puddle. Spoils is less of a mechanic fight compared to Malk. If you can manage sparks and manage the tight enrage you're good.
But yeah I agree, a little ilvl boost wont help bad players do mechanics better.
