the flare have the same range as the regular barrage, 80m and reveal a 30m radius area. That's really good enough where the range is not an issue.
the area stay revealed for 35~40 second. That's long enough for any artillery barrage to finish. The only defense is to vacant the 30meter radius area and to let the soviet have the ground.
Mortar still has to get into range, its not a 1 click anywhere and done like all other recon abilities.
Im not saying its a bad ability , im saying its more involved than other recon abilities.
They made flares vet 0 to make the least attractive mortar attractive, if they are all going to be the same it might as well be locked behind vet again.
Moving flares to vet has been done before, sure on the sniper it was a garbage change but much like the homogenization of the mortars thats what happens when the balance team takes an uninspired and lazy approach to the game...
