I used to play that way, but the new arty rules in the latest update have forced me to change the way I use FO's. In the past I stuck one next to my A0 and used that all the time, not being worried to much about having an LOS.
Getting a .1 adjustment only when there is a LOS means I have to put the FO's up front with the grunts. To get more then 1 magic dime ( golden spot, whatever u call it) I have to buy several Fo's. So I find more of them are dying.If I can't get FO's with 40vis, then if I can see them, they have a chance of seing me. They new rules ARE more realistic in most respects, if you don't have GPS. With GPS and JDAM's, there should be a 2 turn delay ( it takes about 4 to 6 minutes for the bomb to fall from 40 to 60 thousand feet) and the hit % should always be 99% with that 1% being the FO putting in the wrong co-ordinates. No record of a JADAM ever going anywhere other then where it was told to go.
For arty to be useful, you HAVE to have an FO with a LOS to the target. Unless you are depending on your opponent to co-operate by sitting there for a few turns while you get your tubes on target.
If that works for you, I need to play some of your opponents, mine don't seem to co-operate all that much. One itsy bitsy tiny winy little ICM AP round and they are off like Olympic sprinters.

The game will tell you if that tube is being directe at a spotted target. If it is and the target survives, which normal, since arty mostly supresses not destroys, you can use the look around button, or just right click around to see what hexes have a LOS to you. The FO is in one of those hexes. Logic can eliminate some of those hexes, mortars and area fire on the rest will push up the suppression on the FO until it can be spotted. It isn't quite that easy but it is doable.
