If HT bonus room gave rewards to all 12 players for example, people wouldn’t need to multi-client — the profit would be the same using just one character. The bonus room also requires movement and focus to break boxes and loot within a time limit, so no one’s going to loot extra using multiple clients anyway. That means more full parties, faster runs, and more runs per player. Easier to find parties too. If someone really can’t find a party or buff class like SE, they can still mule or multi attack if they want. It’s a win-win. I don’t see any downside or reason it couldn’t work.
