Reason 1: The art doesn't really look like that cell should be passable.
Reason 2: This falls within Selectable Bounds and can therefore be exploited to protect turrets and towers, while making it impossible to collect crates or squish infantry on this cell.
Provided more explanation, eliminated ambiguity.
Where necessary, I wrote "cannot target aircraft" instead of "weak vs. aircraft", since the latter is ambiguous.
Since turrets have wood armor, they can get killed by flame tanks uber fast. It might be best if turrets are a counter to flame tanks, rather than their prey. If they have heavy armor, they will take far less damage, and not die instantly to a flame tank rush, making them able to contribute to some defense.
It seemed from playing noobs that lack of tiberium storage was an issue for them, because I saw them often building silos, often many of them, and they were usually full. Granted, an experienced player should spend that money faster, but I think it's reasonable to give them $2000 worth of storage in their refinery.
It seems that how pips are displayed has changed from before, so someone set silos to have 10 pips instead of 12 so that it fits the reticle. That's fine. But maybe it would make sense to just change that to an even $2000 capacity also.
Since C&C has no power-down button (and since price of power plant went up), low-power is extra painful in TD vs. RA. Also, since the cost is higher for power plants now, it means you will be in low-power mode longer since you cannot build a power plant as fast.
So, the solution is to make the low power slowdown 1/2 speed instead of 1/3 speed for Conyard.
This does not apply to the support queue, only the building queue.
I've been trying to increase the diversity of available early-game build order choices. To do this, I've increased the cost of early-game buildings like Power Plant and Barracks, while increasing the power consumption of the Refinery. This forces players to make choices with more significant consequences. The cost (money=time spent building) of power and barracks are so low right now that the time you spend building them is totally inconsequential to the build order. This leaves very few options, and most people simply pick Barracks, Refinery, Refinery.
Giving some non-trivial time cost to Power and Barracks will allow people to have more possibilities for different openings.
Moved some traits, including MustBeDestroyed, from ^Building to ^BaseBuilding.
Removed some now superflous traits and trait negations from ^CivBuilding.
Changed Inheritances of all buildable structures to ^BaseBuilding.
