Are you the one to win 1 years subscription then? Let's find out. I've put my money where my mouth is so people shouldn't be that bothered if i'm wrong because they get free stuff.
But it looks like you've fallen into predictions 1, 3 and 4.
i do fall into 1, but that's because i had no reason to make the building any different. the simpliest solution was good enough for the speedmapping i did. as you might notice from the pic i posted, it wouldn't be hard for me to change it should i decide to bother.
i dont fall into 3, as my optimization is further down the track and i also dont fall into 4, as i dont consider that a problem and therefore did nothing about it.
25% that can easily be reduced to 0. what you posted are not limitations. they are just the most obvious solutions and anyone who'll bother to do something more complex, will easily find a way to do it.
instead of making your own challenges, you should try to make your own map. if you try hard enough to be creative instead of declaring "this does not comply with my standarts and therefore is bad", you might actually discover that the track isn't half as bad as you portray it.
