The horde section has so much clicking for an idle game... and it feels so difficult to advance if you're not actively involved. So many super short cooldowns. It makes it feels like a waste when you're not actively participating.
Enemies that give you 1/4 of the loot, weird regressive souls design, and other things make the Horde section a real chore. I would maybe take another pass at this to make sure you're not burning people out with this section. I have like 9 equipment slots right now and it's a nightmare.
The Horde section has far more idle than it seems, especially once you've progressed further. Micro-managing your ability uses can really only get you through an extra few zones, with the impact and frequency of this dropping as the game progresses. Prestige time penalty, corrupted flesh, and monster parts all mean that relying on active play only serves to get you to a time wall sooner. You could instead rely on prestige bonuses for such progress.
