One of the best solutions is change it to a 4 man dungeon with less CS, like Aetherochemical Research Facility or Ala Mhigo. The problem is the massive work you need to do, and they have too much things to do and no time for it, so this probably won't happen. If they see a decreasing in the queues for MSQ roulette, they will change it.

A solo instance is a solution, but the worst of all, since it lost their entire purpose.
