my thoughts on how arty should be (if not in the vanila game than on one of the mods)
1. limited ammount of projectiles (not fire missions)
2. player can chose how many rounds to fire
3. limited accuarcy for first round - then adjust fire
4. add option for slow rate of fire (1 splash every 10-15 secs)
5. smoke rounds should last at least 2 mins, not 15 secs
