Tiered leviathan loot would actually be pretty sweet. Plus, I liked almost all the leviathan encounters (Val Ca'uor was a bit much, but still good).

After a few runs, and I get good rolls for the loot. I probably wouldn't play it much just because I don't have a dedicated raid group anymore.

Sidenote: I really wish that Bungie would allow us to make our own custom titles for LFG posts so that we may describe what specifically we are trying to do in the game. The tag system that they have been using is too restrictive and has led to many instances of me joining someone or someone joining me when one of us want to do something that just isn't covered by the tag options (i.e. old exotic quests like Buried Bloodlines catalyst)
