So if I'm reading this right...
*ahem*
"if the enemy knows you don't have any counters they can exploit the fact that you didn't make, nor are making, any counters" is that what I read? What's next? "if I don't cap the victory points, the enemy does and my vps tick down and I don't think that's fair"?
I'll answer that even though it's painfully obvious, but you're missing the point.
They don't know what you have or not, sometimes they just YOLO their way in to take out the med trucks because everybody in 1v1 knows it's going to be there waiting at the front entrance and that they can kill it with one shot and get away.
So again, if it wasn't a problem why is it that easy and why does everybody do it?
If I want to destroy the ostheer's med bunker do I have to make a commitment and take the risk? Yes, and so I will just do it when I'm certain that I can stay there for the time it takes to destroy it.
The same with OKW.
In 1v1 you will see the USF base getting dived on absolutely 2/3 of the time, there is no risk, it's easy and fast, and that's why they all do it.
It's also pretty dumb to just tell us to move the truck when I see he is coming, you think we don't do that?
If it was this simple it wouldn't be a problem.
