I do not have a good name for this one - Get 1 point for each unique room you have had reach RCL6 at any time throughout the season. Challenges include:

• trying to get to RCL 6 without being attacked and wiped out
• bigger incentives to camp and/or downgrade enemies rooms, and to try retake your downed rooms to try get them to RCL 6
• how many GCL levels you allocate to build new rooms vs keeping strong bases for launching attacks or building defenders
• need to move empires across long distances to get new rooms to conquer
• potential intentional respawns to reach rooms in a new area
• challenges of building up 1 source rooms and other rooms that have weird layouts / limitations
• trying to walk through strong rooms that are blocking access to a number of other rooms in a dead end scenario

I feel the Tick 2 could be changed so that if the pullee issued a creep.move(pullerCreep), despite they being technically now in different rooms, the system can check the edge case (here?) and decide that indeed they are still adjacent and as long as the puller itself is moving (which it has to anyway as per any other pull move) move the pullee onto the edge place the puller went last time, and the same square the puller would have been at Tick 3 anyway if it didn't move. then Tick 3 they are both in the dest room and can continue on their journey. This way pulling across the boundary would be as seemless as any other pull.
