Realistic Artillery Management - FOO Rule

[Imp]

Well whats the views on new arty routines.

I am now playing with only optional rule all arty must deploy within 150m of other guns from its troop.

Size 0 units cant call but using platoon leaders has become useful as marginaly better than a FOO without LOS.
No longer do I do arty at end of turn sometimes adjusting before move units.
Chasing units is gone if you want to hit vehicles blanket the area, so forces you to group arty more rather than firing all over the place.
Also means crossing open ground is dangerous as arty can track but broken terrain hard to keep a bead on moving units.
It does have its problems as kicking up dust with barrage will block LOS but guess that happens.
Makes guessing general area units will apear & placing to "walk" on useless unless have a LOS so tends to make you use mainly as support of front line rather than trying to hit vehicles that you just get a glimpse of.
