I dislike the mortar flares idea for Ostheer because that’s a Soviet thing and it kinda feels cheap to copy that for the Ost mortar which also has counterbarrage.
True, the Ostheer Mortar already has strong stats and counterbarrage. USF Mortar could definitely get something to make it more attractive though. Currently it has worse stats and no actual veterancy ability besides faster smoke barrage cooldown.
Personally I think Ost is fine since Pios get Vet 0 42 sight from the start and are usually in the mix either sweeping or repairing. For USF I think it's worth mentioning they get Pathfinders doctinally and I wouldn't discount the Major's recon ability. If anything I say Officer Sight Toggle and Pio Upgrade would be the way to go but don't feel it's strictly necessary
USF probably has it a bit easier with its doctrinal sight options. Their 1v1 meta doctrines have either Pathfinders or Combined Arms (either mech/recon/cav was chosen 87% of the time in WCS), which are both good sight options. In terms of Ostheer's 1v1 meta commanders, there's G43 Pgrens with Lightning War and Jaeger Infantry and Recon Overflight in Spearhead, but with other popular doctrines like Infantry Doctrine, Mechanized Assault and Osttruppen, there's not much to do aside from keeping your 222 alive, Pio sight not being that impactful in the late game.
While I think it's good option for engineers of all factions to be more useful, it will take away the necessary of light vehicle (Kubel, 222, Bren, M20, Scoutcar) and leave it with only anti-sniper duty.
So unless you can improve roles of light vehicle, I would choose no.
Problem is, the durability of light vehicles differs greatly between factions. The 222 has 320-340 hp, while most other light vehicles have 400 hp. Captain tech doesn't have a vehicle with good sight at all. Something like the M3 has 65 sight with veterancy and can take an AT gun shot, but they're not expected to survive till the late game. Meanwhile Ostheer is supposed to keep their fragile 222 alive against UKF and Soviets, which have increased sight on many of their units
I'm more for the scout cars. Get the M20 & 222 a recon ability like the T70 (withou the soviet capping thingy). disables the gun, gets them 15-20 extra sight.
For the 222 it should always lock-out the spotting scopes.
I like this idea. I personally already keep my 222 on hold fire anyway when spotting with it, because it's hard to keep a solid frontline against Soviets and UKF if you lose it. I'd prefer at toggle with 20 extra sight to increase the buffer against SU85's and the like just a bit.
Giving the lieutenant and captain a sight bonus at vet 3 instead of the damn running would also get my vote (10 extra sight?).
Would like to see that, passive sprint has been gradually getting replaced on units cause it's kinda cheesy.
