If you are to make any larger demand changes than the ones you've made so far, I'd make it an alpha test and wait for the next round to actually implement them. Most people here will probably support you if you do it this way.
The problems with demand were, as far as the beta test is concerned, mostly due to little testing with small aircraft, for which I might also have to take some responsibility.
To explain this to everyone: The beta-testing for the new create route script involved testing with existing aircraft from that round (ie. the last one), which in most cases were large aircraft (737 and higher). That might mean the new script, specifically the effects it had when dealing with small aircraft, have not been trough the testing they should have been, looking at the results from this round. To be fair, it's really hard to judge the consequences of the script in a new round, when all you can compare with is the existing round. It might sound rude, but this can happen in a game that's under development. No-one claims this game is perfect, and problems like this can come up all the time.
A solution to this problem is being worked on, so try to help us out as much as possible. See how the round progresses, and continue to give us feedback on the way things are right now, so we can improve the current system.
