Pre-planned arty fire on setup zones

[O' Murchadha]

I have a question regarding the targeting of anywhere but the set-up zone on turn one. I ask because, one function of arty is to deny your enemy access to certain terrain. For instance, an important hilltop (not in set up area) will be targeted if I think it will eventually house a FO team. A main road into an OBJ or key terrain, to deny use of said road. Anybody see this as too gamey?
