Cons are fine. In fact they are too effective at being multipurpose. Molo is too cheap, oorah negates gren effectiveness immediately , insanely cheap to reinforce, Can merge. What more do you want?
Molotov requires gas to unlock, has the second longest throwing animation of any grenade, and is VERY RNG prone, as well as being easy to avoid by virtue of being a DoT.
OOorah is the very only saving grace of the unit. You cannot spam it every fight, and once Axis elite infantry/LMGs come out it's only use is chasing tanks for an AT nade. It most certainly does not negate grens; you need to run over cover or else you might still take losses and lose the engagement either way. Once LMGs come out it's suicide to charge a gren squad.
Cons aren't any cheaper than any other squad to reinforce. Half the cost of the squad. In fact they cost more to reinforce from 1 man than grens.
Merge is useful if you field Guards. That's it. Weapons teams are cheaper to reinforce and Shocks losing armor is not worth it. And even then, it's like 10 MP per model that you save. So OP.
What more do I want? How about being combat effective past the 10 minute mark like all other core infantry? Conscript's benefits are marginal at best relatively speaking. Grens get great vet and the beastly LMG. Volks become among the toughest infantry in the game bar Shocks and scale thanks to free grenade and shrecks. Rifles scale pretty well and have access to good weapons as well as smoke. Conscripts need a 45 fuel investment to gain some utility, and still lose 1v1 to every single Axis squad bar pioneers and Osttruppen unless the opposing player's micro sucks and he eats a molotov.
We're going off topic and I will stop. It's painfully obvious talking to you leads nowhere.
