Don't sweat it everyone makes mistake.
I was mixed with the other commander howitzer ability, counter barrage that also uses the howitzers. So yes I concede that point to you, I made a mistake.
>50 fuel
.
It's not just 50 fuel though is it? Do you really want me to add up the entire MP and fuel investment to get to Anvil shellburst?
Anvil/hammer imo is worth its cost easily. You unlock a vehicle and get 3 bonus abilities.
Ask yourself this:
Is there any offmap in the game that starts off as weak as concentration barage until you dump a load of MP and fuel researching up to Anvil? Imagine if Stuka Dive bomb only dropped a single mortar round until you researched Ostheer Tier 4. Then upon researching for the Stuka divr bomb and Panther you were locked out of the Brumbar/werfer... this is the life of brits
There would be outrage yet this commander is left in the dumps
Ask yourself is there another off map at CP4?
Again you do no need anvil for concentration barrage it add nothing to the ability. Unlocking Tier 1 gives you access to it unlocking tier 2 gives you a second gun.
