It's a trade off of survivability for effectiveness... don't really see the problem other than not being as satisfying to outflank. I believe since the patch the German mortar does more damage and fires faster than the 82mm one, while the 120mm is more expensive. German MG has a much more satisfying firing arc and the PAK is definitely better vs. what it has to deal with than the ZiS. In addition to which, Russian weapons teams all come at the expense of elite infantry production, while German weapons teams don't.
@CombatMuffin - if the Soviet has a number of weapon teams you can probably invest in a mortar without losing too much capping power.
6 is fine probably...but all 6 members have the same health-per-man as the German 3 man teams. Doesn't make any sense.
Makes perfect sense, trade off of survivability vs. effectiveness.
Horribly chokey maps are a problem all of their own, but the Ostheer have a fair few advantages on them too.
