nope stays the same and just be as cost effective as the rest of the vehicles in the game even with the nerfs
Bit of a knee-jerk over-reactive nerf to the M3 in my opinion if you did that. You want to cripple it's ability to do damage (taking note that a properly used M3 is meant to shoot from max range to avoid faust so generally you will be using that accuracy profile to calculate dps anyway) and reduce it's paper thin armour even more without a reduce in price? What player who can calculate the value of a unit would ever waste resources on that?
I would have no problem with the M3 getting a health reduction even if the cost stayed the same because if you use it well it shouldn't get caught. That way it couldn't absorb so much hits and bleed German MP without needing to fall back for repairs.
