I voted for improved MX. Currently, I am in a private world and my daily MX costs the last four game months have went from 26M to 12M back to 26M and back to 12M. I also think it is more realistic (in this game setting) to keep airplanes for more than 3 years, which seems to be the consensus on replacement age. Furthermore, due to MX costs, I refrain from buying anything larger than a 767-200ER for long range operations. I think improved MX costs will allow for a step toward a more realistic AM!
