No arty gets any dmg boost anymore with vet.
The LeFH's gun when it's vet 3 is an entirely different gun then when it's vet 1 or vet 2.
I'm confused with people having success with counter-barrage? Like Iv never had it work except when facing really terrible opponents who refuse to ever move their shit ever.
A nerf to the ML-20's shells might work.
At Vet 3 the LeFH has practically zero cool down time between barrages. Coupled with a Arty Officer which can over ride any cool down with his ability (and increased range!) and I think the LeFH is in a wonderful spot.
This is because it fires so many shells. But if the opponent moves and you need to reposition you get the same cooldown.
