I disagree. Other flares don't need to be changed because arty flares need changed because other flares are not the problem. Other flares need an entire unit somewhat close to what you want to flare, arty flares needs you to be able to click twice. It's not necessarily the mechanic of flares that's the issue but the application. The only other flare abilities that isn't tied to a unit are brit ones that they don't actually have control over its location which do a great deal to lessen their impact.
It gives the WHOLE GOD DAMN FRONTLINE and that doctrine also has shitloads of arti + offmap.
