Not quite as good as a recon + bomb, but there's still storm doctrine- tactical movement [sprint] with pioneers [long line of sight], then stuka? Not practical for the soviet player to cover every single angle of approach, especially for an out-of-base howitzer.
That being said, it's the only thing storm doctrine seems good for, and the soviet howitzer doctrines are definitely better. Only LEFH doctrine that seems decent is the one with scopes and command tank.
Ahh yeah you're right. Storm does have Stuka and leFH18. It'll definitely work against out of base howitzers.
Either way the out of base thing is a great change, and right now the ML-20 is crazy. I don't think there's anything wrong with Relic experimenting with the leFH18 being stronger. If it doesn't workout, it'll be pretty obvious and they can buff the ML-20 or slightly reduce it's cost.
