Give the wall sappers a lift...

[Aurelius...]

Tanks can't break walls, sappers/engineers can. But sappers/engineers only really get one shot and can't easily break inner walls.

My suggestion is: allow sappers/engineers to board and exit tanks. When a tank reaches a maxed inner wall and can't break it (due to ridiculously low dps), a sapper/engineer or two can be ejected to do the dirty work.

I always thought Engineers could ride pillion on Motorcycles too.
