That's not such a serious problem, but still, something should be done about it:
Flare mines - vet 1 ability of most part of soviet infantry. Soviet infantry is definitely not best in game, some of them are even really bad, like Cons. And in addition to that Relic gave them veterancy ability which I never (again, NEVER!) used myself or saw used by ANY player for my 3 year playing in CoH 2 experience. And I'm sure, that there is very rare chanses to see anyone who would use that ability and more rare - gain something from it.
Of course, some could say, that it is "free and cheap vision", but right now USSR is full of vision stuff. Recon planes, Mortar's star shell, sniper's light round... And all of those tools are way easier to use for sight, than putting flare mines. Using them just takes your and your units precious time. I guess, that is a reason, why 99.9% of people never use flare mines, and even more - forgeting about existance of such ability.
And of course, you could say, that Ostheer's ability is quiet useless too, since you can just build Med-bunker and heal them easier, than just every time spend 20 muni on med-kits. But, med-kits are actually usefull and I use them often to heal soldiers on frontline, when I just can't order them to retreat and get healing after hitting them by mortar shell, for expample. That's not always kill someone, but may damage all sodliers in squad tough, so you can just give them medkit and don't call them back for healing. Healing at frontline can be really important, as you can see. But, it should cost cheaper, 10 muni maybe, since UKF soldiers can use same healing for free at all.
My suggestion - not so long time ago Relic gave to OKW intresting doctrine, Overwatch doctrine. There we have "Early warning" ability, which automaticly puts flare mines at all captured points. I suggest to make vet 1 "flare mine" ability work same. If point will be captured by vet 1+ soviet squad they will automaticly put there flare mine.
I don't think, that it will be OP somehow, cos flare mines make no damage and giving only 8 sec sight. So, nothing really significant changes, but people will start to use flare mines after that. Ok, game will do it instead for them, but still, it's better than have totally forgoten ability in stock, like it is today.
P.S. Moderators or someone - change word "decision" in name to "solution, pls. Bad knowledge of english causes such mistakes, sorry.
They actually DO cause damage. I may be wrong but I think people used then during ESL to plant on doors which caused Fallschrimjaeger squads to get instawiped upon spawning.
