Before I started to expect more realistic penetration effects from the game I think I would have to start with having them have more realistic ammunition loadouts because the ones they currently have are pretty silly, so I think once they get that sorted out then we can talk more about penetration effects.
The real issue I have with the tanks is that every infantry player can kill you in a heartbeat, and the planes can fly down to point blank Range and drop a bomb on you and kill you in a heartbeat with no danger to themselves because the bombs all have a delay on them not long enough for you to get out of the way but long enough for them to get out of the way
And I totally agree about the obstacles on the map some of the campaigns are so cluttered that I won’t even take a tank out on them because it’s too frustrating, and if you get the tank stuck you have no way to unstuck it so you have to abandon it which is pretty frustrating as well so there is definitely some room for improvement here
