I was experimenting a few more ideas, especially grenade angles, and also wanted to clarify a few things above, as well as some further suggestions/arguments.

First simple one, the shape given to the wall blocking Short A from A Site can maintain its jagged shape, if the entire wall just creeps back those 5 grid units. I don't believe it exposes too much more of the site or Long A from the ladder balcony.

I watched all of the videos from the inception to his last one (the last being why I wrote this in the first place), and noticed that the ladder balcony on Short A was supposed to have no line of sight to CT entrance to A Site. However, even with the current version, it sees a gap smaller than the Mid Door gap on Dust 2; cutting back the wall allows the T to see the entire gap, as feet weren't visible on passing CTs, but I don't see it as needing changed as it's a hard shot to hit AND only happens if the T is lurking for a rotation kill.

The ladder balcony also could be fashioned after a loading dock, seeing as the overhead wall will look a lot like a garage door, and also the ladder may be preferred as a ramp. When given textures, it would be a garage like room filled with boxes with only so much room in front of them, and a small set of stairs (could have a railing alongside if it doesn't take up the whole width) would fit right in, and of course would be clipped to act as a ramp to avoid the view popping up with each step. Bouncing a grenade off of the wall above the garage doorway would allow a smoke to land gracefully next to the tall box, blocking off the majority of Short A from A site with the changed wall mentioned before. This well-placed smoke can be carefully skirted by the Ts to clear the box to the side of A site.

Since we're on the subject of a loading dock and the tall box in Short A, that box could be a forklift, likely facing away from or towards A site, so that the fully raised fork blocks the view entirely through this axis.

The wall next to the connector to mid and side A box can be used to bounce grenades off of for both teams, especially a well placed incendiary grenade to either force the Ts to wait, or risk going into that well placed smoke. However, from the T side, it's just shy of enabling a grenade onto the actual A site (without exposing yourself, even without the wall being cut back), especially when trying to deal with the CT likely hiding behind the short box on site. Making the wall a bit wider towards the side box is all it takes to enable a grenade to land on the short box more consistently, and also effectively blocks line of sight from A site and CT entrance to Short (especially the box).

Also, I noticed that a CT watching mid or on the Long A balcony can throw a similar incendiary as above to block off the perimeter around the smoke, including behind where the reduced wall will place the box.

Lastly, I noticed that you can surf UP the slant next to the loading dock platform, giving that extra bit of height to silently (other than a running start) get onto the platform from the CT side. Cool little detail that may or may not be intended, but also a very vulnerable move if a T is lurking near the T entrance (but hidden from the T entrance itself).
