When you kill a vehicle by knocking out all crew members, the tank either bursts in flames or explodes which doesnt realistically happen unless you hit their ammo, not only that but immediately after they die the tank gets this old/rusty look:
This should only happen after over a few minutes, the tank slowly fades into this burnt out old texture.
Also High-explosive shells are very unrealistic in Warthunder, such as the HESH on the FV4005, you can shoot (lets say an Tiger 1) on the side and less than half of the crews will get hurt, when in real life a shell struck there might just blow the whole side out or even the turret flying into the air.
Not only that but Gaijin keeps adding updates instead of fixing the game script, this has caused the game to become very unstable and glitched.
I often encounter bugs/glitches ingame, such as the ground getting a wierd multi colored pixel texture at some angles and shells bouncing around tanks in the Hitcam, i think its time to Re-Write the game script as Gaijin keeps stacking temporary solutions instead of actually fully fixing the problem BEFORE adding new stuff
Please take this as a consideration to make the game better!
