You can't pressure/force random players to speed run in a matched PotD. Some players want to grab every single chest for intuitions (hoards) and consumable chests for a chance of potsherds. It's all money (i've made millions this way)
A premade group is the way to go and you can 51 to 100 in less than an hour (or much less) If they leave after X floors then that's on them.
Edit: With everyone maxed out. There's also PvP as mentioned. While not fast it's a fun way to get Lore.
