Knights, we all know that our greatest assets on our dangerous dives into the clockworks are our squad mates fighting by our side.
Fear a new level design where we start off separated from each other and must fight to get back together. This would encourage people to run parties, as each player would only have access to 1/4 of the level or 1/4 of half of the level, depending on how the gremlins construct it, and thus more players means more map covered meaning more monsters fought meaning more loot.
Unfortunately, this would defeat the point of playing as a party, since you'd effectively be playing solo, and it would leave solo/small parties with half the map to explore.
