The Concentrated Artillery Operation ability is very similar to the Ostheer Railway Artillery. BUT it doesn't require line of sight to use, and it's so quick the first shell hits the ground(about 5 secons? If I'm wrong pls correct me). So the first shell is hard to avoid since you never know where it will hit.
This is very much correct.
On the other hand, it's a big waste of munitions(200 munitions is too much)to use the Railway Artillery for the OH. It requires line of sight, and it's much longer the first shell lands on the ground after the warning smoke.It can hit nothing unless the enemy is sleeping.
It's meant to smash up defenses not that the allies build many static defenses.
So why they are so different? BTW,there are always better version units or abilities for the new faction, another example is the 6 pounder AT guns cost 280MP and 7pop.
They are different because different factions have different strengths. In the case of the AT gun, the QF6 Pounder cannot be garrisoned in buildings and cannot be supported by a mobile rocket troop and thus is cheaper than a R-43, a Pak fires very fast and so it is also dearer. Prices don't just show the strength of the unit but also it's faction so expect AT to be expensive in a faction that can spam a lot of decent AT out.
BUT this time,don't nerf the Concentrated Artillery Operation. It's fine as it is, so buff the Railway Artillery to make it usefull.
I agree with this but still say it should be weaker than the Brit one. The VBrits are built around great late game units and abilities, it's their saving grace. Ostheer has the dubious advantage of having some of the best speacialist units but also being reliant on them. A slight decrease in first round hit time wouldn't be bad maybe 5 seconds down to 4 is reasonable or 3 seconds in exchange for less AoE
