The stun resistant enemies are definitely annoying, but I didn't have too much trouble with the capacity filling gimmick outside of bosses on my vore setup. Bosses spawn entirely too many adds to deal with though so I just tank and get my DR up to 95% punching the boss until it dies. For the recycler, I kinda wish it would drop gear of the level of the last stage completed instead of the minimum level of the current world but other than that it's fine.
