Reason 3. It would be nice to see other tactics implemented and tried out. At this point, in a modern times scenario, one could simply make this sim all boeing/airbus with the dash8, atr, and saab. The 752 is very imbalanced due to benefits from frequency. Why fly one widebody when 3 narrows will do?
Because of how small the world will be and knowing how ineffective widebodies are, the 744, a340, and 777 will be useless if the 757 is in game. The queues for the 330 and 757 will be full.
You may disagree and that's fine. It was only a suggestion.
