One way to work around it, is just decrease the maximum amount of monsters that can spawn in a floor. Say, from 5, to around... 3? It can be jarring how some floors have just 1 monster to kill, and the next couple of floors 5 monsters.

That way, we can keep the higher levels (and thus, better chance for better loot, or at least 10 star loot) thanks to more floors, while still decreasing the time needed to clear each floor.
