It means if you're bad at driving platform you need to make an easy track so you can drive it flawlessly yourself, and then lose points because your track is easy to ace. This is holding me back right now: I can drive each individual part just fine, but I can't string them together without crashing somewhere.
To me, creating a platform track and uploading it without being able to drive that 0-restart run yourself is a bad idea. Driving that 0-run on your own platform track is just as important as setting a fast AT on a normal track. It forces you to become very familiar with the track. You learn things while you're trying, and the track often improves as a result of changes you make during that process. If you spend a lot of time driving your own track during the building process, and improving, then that track will almost always be better when it's finished.
TM2 allowing you to just
set a 0-restart AT without actually having to drive it is silly. Why not allow builders to set any AT they wish on normal tracks? I don't think people would appreciate that very much.
Anyway, I can understand your frustration, believe me, but I think requiring that no-restart run is a good thing. At least you can work on getting better at individual CPs in the editor without having to drive the whole track each time?
(While I'm at it, why does TM2 not give you the option of saving a replay when you validate a platform track? Also, why does it not automatically create a media tracker ghost when you validate your platform track? Both of these things don't make any sense.)
Edit: Also, a good platform track doesn't have to be super-difficult. Sometimes easier ones are just as much fun!
