I've suggested this maybe 2 years ago. Nobody liked it. Bridges won't be that important if you can travel by air.
I once suggested to add buildable ramps for engineers, and it got ignored/refused, so I guess this will be even more ignored.
even the most experienced players sometimes only place one flimsy wall segment and quickly get raped, so i don't think that a tutorial will be of much help.
I have to admit I don't get the reluctance to use walls. Quite often you can close off an entire front using them, very useful when they're in ur base killing ur dudes.
Who are the most experienced players? Because if you dont know how to use walls you're anything but experience, you might want to review what experienced means. I use wall alot as infantry, even more as commander. 90% of the Commanders do not understand that walls can stop a rush, even in scrim I see commanders being afraid if rushes when all they have to do is place 2 or 3 layers of walls. Conclusion : whoever does not know how to use wall effectively isn't experienced. And, you're terrible a judging people apparently.
its also great to drop your dudes some wall pieces for advancement if they are not doing it for themselfs. actually its best to wall off everything on a map apart from your primary supply line/attack route - the few seconds recycling them hurt a lot less then the few seconds it takes them to destroy the wall ...
