Trenching with a shovel definitely has it uses and benefits, but there are also times when it should be able to do just a little more.
Suggested change: make the alt-fire of a shovel, activated by the “aim” button, flatten the terrain. If aimed at the bottom of a hole, it will flatten the terrain as best as possible to nearby terrain at the same depth. Same type of effect if used on normal ground, removing soil that is higher that the starting point. If aimed at the side of a trench, it will smooth that side out to be an easier to traverse angle. This is useful both for infantry and for tanks to get out of trenches.
This addition would allow for more effective trenches for infantry, better building locations for engineer fortifications, and better traversal for tanks.
I swear this must be the first time I have seen a forum post received a ‘100% approval rating’. It is a really good idea from OP though, and I hope that the developers would be keen on adding this feature. It’s just one of those quality-of-life mechanics that would be beneficial to everyone involved!
