The idea is that when parties (or players) tries to queue for dungeons, the dungeon would put them in a queue list to enter on a first come first serve basis, this would eliminate all sorts of unfairness and uncertainty when then player/party are spamming over entering the dungeon.
(This is especially crucial for Telsiai due to the huge influx of players and traffic when dungeon resets, it goes on for more than just a few hours.)
The same concept applies to party search where players are being put in a queue until they meet their teammates which assumed are also in the top queue. Sick of these “Please check after Mission Instances Excess Count”, doesn’t even make sense, I still have two runs left IMC, Christ.
