I can see what you are saying about Duelling Dragons, and it probably would save time with unloading at the first station, moving forward, loading again etc. But the problem here is, if IOA changed it now, They would only be able to run 2 Trains on Each side when IOA can ACTUALLY run 3 Trains on each side(Some people keep thinking the Dragons do actually have 2 Trains each, but if you look at the transfer sheds to the sides before you set up the lift, you can clearly see a 3 train for each side in them) and Personally, I dont think IOA will change it, because DD actually has the highest capasity of any coaster in the world when you combine both coasters together(192 People can be on the ride at any one time when 3 trains are running on each)
