Pio sweeper caping will loose against every infantry on the game, "MP management on the map" is quite "necessary" when you can loose your squad (or squads if you blobbed) with 1 button
Panzerwerfers decimate blobs better than the Katy, because you get 10 rockets on target in 1 volley, vs the Katys 4-8 before the blob has retreated out of the target zone.
Lefh is actually surprisingly decent in 2v2. It doesn't suffer from the same problem as other arty pieces in that it gets killed easily by a certain Ostheer doctrine. I've been using it more in 2v2 and I have reached good results with them. It's not a 1v1 unit though.
- Try to count in a week how many panzerwerfer you will see, and how many katyusha you will see.
- So lets count ML 20 and B4 in the list if you think lefh is "surprisingly decent"
Note : I will never defend CAS
