I think the instance is fine. There are options to it, instead of the instance dictating how you must tackle it, which is very nice to have.

Secondly, to the OP, if you're not a fan of the parties that people make (I can understand, not everyone likes to do things the same way) my suggestion would be to start creating your own parties and underlining your goals to the group beforehand, I'm sure you'll find more like-minded folks who want the challenge of clearing the trash + instance.

In the meantime, I'ma run from the toads/hypos/moles/etc... Sh*t's scary.
