I love the current set up. If you wanna rush to the boss you only have to clear one goal. If you want to take you time and build point's you can go for a full clear. There's a nice little level of strategy in there to make things interesting.

I agree with Demon about the main boss thing tho. But I'd be willing to wait for the KI increase before adjustment's.

How about adding a rare chest drop from any mob in meeble's zone that contains one reward item from the tier's boss mob? Could make it like a 1% chance of dropping. Or maybe even add it to a random nm that could spawn in the zone after entering. Could add a interesting perk to any run. Please no log's or rock's.
