Commandos without moving camo '@vet0' wont be a soo bad...no one is asking for completely removing them, just move it to vet2/3.
They would be quite an investment. MP heavy, Pop cap heavy, not really durable. And giving them at weapons takes away their cqc-power. I think it is fair. I think, it isnt much of a problem, since this is the first time i have seen this strat. GUess it is a rather nieche one.
Everything here comes down to a l2p issue. The amount of work you have to put in there to make it work is beyond good and evil. In over 2500 hours of playtime i managed to make it work in 4v4 on time (vielsalm / stuka + killing a cache with storms + shrek) and killed 2 russians asap. It is realy satifing but the counter play is way stronger.
Surplus, if 4 people manage to work together to pull it off, investing a lot off munition without a 100 % of sucess; the enemy doesnt deserve to win in the first place.
