Its actually stupid.

that Dark Harvest+Duskblade is a guaranteed 1shot on any non-tank target.

Nocturne ults, youre with your support.... what do you and your support do? Nocturne gives no shits about you being protected. Support pre-emptively use Lulu ult on your ADC. LEL ADC got 1shotted anyways. OH CRAP DARKHARVEST RESET, LULU GOT 1SHOTTED TOO LEL GET GOOD NUBS.

balanced.
