Observations after a month of playing and testing:
Is there a reason why some sappers have the short sword, and other nations don't? If there's no major reason, I'd like to see it consistent (all have, or all don't).
The trapezoid shape makes it incredibly hard to line up sandbag sections without holes. Changing from the rectangular shape gives us two choices: build closer together (reducing surface area of cover) or accept the gaps (compromised defence). One flat surface at the top would appreciated, without the V and raised sides.
For whatever changes the sandbags get:
Could you test building a wall of sandbags (lets say 4 wide and 2 high) on a slight slope? Does it leave holes? Is it easy or finicky to build?
The small hitbox is by far the worst part of sapping. I've tried my hardest to adapt to it, but it's just so infuriating. If I had a bitcoin everytime someone got in the way, or a horse smacked me, I'd be richer than Bill Gates. It does make it harder for 2+ sappers to rush build. Please, please restore the hitbox sizes.
