I understand what you mean, but I don't think you understand me correctly.
The problem I'm having with ghillie suits right now is the fact that there is no specific environment in which it camouflages well in. I spent an hour or so with a friend of mine comparing the visibility between the ghillie suit and a standard uniform (we played hide and seek :))and I can tell you right now the ghillie suit is not effective in any specific environment, at least on Stratis. I don't know the topography of Altis, but no terrain fits correctly with the color scheme of the ghillie suit on Stratis.
In ARMA 2, the ghillie suit was extremely effective in hiding prone in the grass or under the pine trees, which was basically 90% of Chernarus. You could literally hide from someone in plain sight if you were prone on the grass and facing the right direction. The ARMA 3 ghillie suit however, stands out as much as a standard uniform regardless of where you're at. It doesn't help to be wearing NV goggles (which I consider essential equipment) as it's colored in desert camo and sticks out like a foot from your face.
