No, that's not my reasoning behind this, I'm simply supporting the argument that buildings should have as strong a functionality as cover does, but not too strong, which is why flamers, mortars, etc do well against them, as well as small arms fire, but don't limit it to cover equivalent to yellow cover, at least make it sturdy enough where units aren't thrown out instantly, but not to the point where they can stay in it for a long period of time. I recommend a 5% increase in benefits, which I believe is fair.
I thought that building give slightly more than yellow cover. Also as people stated you are not getting suppressed and Armour doesn`t rape you if your in a building.
But maybe you are right, I am just a low skill noob who you raped with a T-70 spamm =)
