It still amazes me that to this day, adept drops aren't guaranteed from either, yet all the timed events that require less than half the effort keep getting better rewards. Availability shouldn't matter, but difficulty. The game and several sources classify the Nether as a "nightfall". The difficulty may be labeled as "expert" in Nether and COB, but Nether increases enemy levels the further you go to the point they all have skull icons, something no other activity does unless you're going in significantly under leveled. Skulls meaning they're 30-40 above you, meaning higher than GMs and Master raids. Still, adepts aren't guaranteed and there's no way to increase these drops except just opening boss chests. As for COB, they are scaling up to master if not GM levels. Randoms often seemingly being adamant on doing everything the hard way, leaving 1 guy to take care of augments, or using the worst loadouts. Then the fun with the augments themselves, like placing objectives just a few feet away from enemy spawns, bosses hiding where you can't see them with Ritual or constant map hazards like Lucent Hive's purple spikes or Taken Ignition/ Isolation, Bound bosses not always moving away from each other, or needlessly stacking defense augments on top of each other like Sharpen and Bulwark. And what's the reward for killing 13 bosses with several minutes to spare on the off chance you get a competent team? Regular drops more than half the time and if by the off chance you get an adept, it's either not the one you're looking for, or the roll is trash with no way to increase the chances of a good roll unlike literally every other adept weapon in the game. If you're going to be that stingy on seasonal adepts, I'm not looking forward to how hard or unlikely T3-5 weapons will be in EOF and can think of no logical reason why we can't craft adepts or weapons equal to them.
