That was the consensus of those talking in TS last night before you arrived.In the GCM, gun crews are reduced from 15 to 10. Garnier did that in an effort to make counter-battery fire more effective.
But, obviously, that's not working.
". . . but I think??? everyone is starting to come to a consensus that they prefer the 1.2 stock artillery for the most part."
Not sure about that as most of us MP players haven't played with the stock (1.2) guns.
As for the reduction of gun crews, the intent may have been to improve counter-battery but it didn't work as the critical factor is the number hits scored by the opposing gun crew, not the size of the gun crew. All this reduction has done is once again tweak the game to favor infantry. By reducing gun crew numbers by 33% it increases the speed that they rout when facing infantry. Gun crews of 15 rout at 6 - which requires a loss of 66% of the gun crew. Gun crews of 10 rout at 6 which requires a lose of 40% percent of the gun crew. As counter battery fire isn't effective and infantry fire is, this decreases the time that batteries can stand up to infantry, which further decreases artillery's already nerfed ability to defend itself with rifle ranges at 220 yards and decreasing canister effectiveness by 1/4.
