Yeah, that's one of the better solutions I've seen.
People keep hammering that they want to add the drops to the loot pool, but utterly fail to do the math and logistics involved.
1% droprate on 18 people equals 16.5% shared droprate, so SE would have to nerf droprate just to keep people from obtaining everything in a single week.
And then there's the treasure pool limitations... if you allow 18 people dumping everything (including the kitchen sink) in it, chances are that that precious Toci's Harness is assigned to a random person anyway, if not outright lost to the void due to the logjam preventing anyone from lotting in the first place.
Point systems similar to einherjar to buy Toci's Harness wouldn't work either, because then people would simple spam the most economic NM for it and get everything that way. Specific NM points might work better, but even then you would only be able to buy Ocelomeh Harness, not the +1 or Toci's...
