I'll throw a curve ball and say that we have gotten lazy, obtaining information is too easy via scouts, hardly ever you can do anything more tactical at t1 and by the time t2 or t3 rolls out it becomes (in most chases) utterly pointless.
The problem is mostly t1 air scout being too good of a scouting unit and jack of all trades when it comes to it, and it will probably stay that way.
Even if we add all proposed changes by some miracle, i would argue that it is all meaningless since one little scout can reveal the whole map with no setback to the player.
