Optic HQ improvement

I have noticed mafias and terrorists can easily access the hq  but the mountainous rock behind the building where they get onto the roof, as much as that they can spawn kill optics. Mafias hq isnt accessable easily  but optics is. Have a look at the screenie showing how they can get in

They get down from the massive rock, onto the roof, down the stairs, this means they can easily kill optics who are killed and spawn again, im asking if you could put an object, like the rain shelter from San fierro train station by wangs cars, over the HQ, or something like that.

Sincerely

Contact Amir for this, if says yes then i will change
