My last one I had was just a square box with either 200 or 300 mobs, which included those dark orc fire and ice archer mobs. cant drag anything anywhere because i'm being hit from all sides, rt and its just as bad, can't bring pets in to help as they get killed real quick because there getting hit from all sides. They are not fun to do on a wiz. Not easy to take the damage even with 8k Health. Not fun at all.
The things they request are generally ok although I may just be lucky (but don't even entertain the myth essence or source requests), as Coldanvil has said above with myth item drops being scaled back, even more during events, unless your on a GG private cave. Surely it would be better to have a skip feature? but then you have to wait 24 hours to get the next one or just change them asking for it in the 1st place.
