Sadly but useless area to farm. For 2 reasons: 1. Too strong mobs+level lock. 2. Almost no one is interested in special drops from there. I've seen like 4-5 guys buying effigies for this 3 weeks. No sense to farm them especially bcoz price isnt high at all. Seems like uber is designed for those rares who wanna really beat ALL game content no matter what. Overall it's cool idea (i dont care if it looks like poe maps, it's ok), i dont regret about time i wasted there, good exp on high tiers also gives it some priority. But anyway looks like a place for those who specially loves to run such things rather than a typical grinding place. Maybe it's even good, who knows
I agree also that level lock is pointless there.
