I ran this a few times with my friends and noticed there's not a category for it, after looking on the forums I saw that it's because you can't repeat the mission after it's gone unless on another character, a friend has it, or on another account. Then I noticed that the mission "The Archon-Slayer" was on the IL list, which was bounty based and is no longer available at all. So my question is, can we include "non-repeatable" mission like this on the list? I think it'd be worth having on there in case someone actually wants to see what a ran of it looks like. That annndddd I already did runs on it... ^.^;

There are rules for this in place. Anyone can attempt it at any level. Hypothetically if you kept wiping before killing the boss you can beat the first (non-repeatable) level at 40. Mods are always checking the forum so they can tell you

Just leaving this here, we did the mission at least six times and it comes back to being playable on the seventh every month until reset from the seventh.

So now the mission is doable at any time, can it be on the leaderboard yet?

it becomes available once you turn in all the items, you just don't have to wait until the 7th now, it still goes away once you complete it. I've checked multiple times when I go into the directory, I can't select that mission anymore.

it's more like the quest line is doable at anytime

I can do it again? I've done it at least five times now

has the character you're doing the mission on completed the entire sleeper quest line? Because my hunter has, and he can no longer do that mission, I even just checked to make sure I wasn't blind.

Oh no I haven't I just completed the quest and stopped ^.^ Good to know I suppose ^.^;
