I can confirm that Katyusha is definitely too good in team games. It destroys trucks... wait actually it destroys anything.
One single rocket will wipe a squad (I had a single rocket wipe a squad + kill 4 models of another), and several rockets often land in the same tight spot.
I just had a game where a guy spammed Kats. Luckily he was bad as he failed to move them after firing, so I could kill 8 of them with my Stuka (vet 5 in minutes thanks to 1000+ xp per kat), and my teammates were shooting at him too...
They need to be toned down a bit. People say that you can avoid their damage completely because it comes in waves but it's wrong. More often that not I retreat just before or right after the first wave without losing anything, then the last couple rockets will land in the middle of a squad, wiping it...
I'm not saying it should be nerfed to uselessness as it was before (unless HEAVILY spammed), but it's way too good in its current state.
Played only two games with it
