S-mines are fine now and really easy to deal with as pointed out in earlier posts. It's quite amusing to see people calling it OP when a bloody soviet mine is useful against both tanks and infantry and can one shot a vet 3 PG squad. Oh and might I add soviets automatically have access to demo charges without having to tech for them whereas the Ostheer do not.
I think they should change the demo like the American one, (place a wire and demo it) that commando demo is too crazy now, because even you know the demo is here, you cannot do anything. It will be more balanced if sweeper around, demo cannot be ignited.
