kat's make god of war look very lame, if GoW is made more powerful It may be overkill to have the god of war and kat's on the same doctrine
anyway something needs to be done with it, maybe more like sector arty or yank howitzer barrage, but really it should be something original which is i sure what the devs intended
it needs to reflect the quote from which it is named 'Artillery is the god of war - Stalin
maybe if it barrages at a not too hardcore way with long cooldown, but uses the strafing run template for its hit area, as though a commander was trying to focus on an enemy defensive line.
with prop being the only doctrine allowing russ to supress early it seems likely that defensive lines will be forming on both sides.
good luck devs
