It seem rather early to provide useful feedback but there is an ability that is so obviously bad that need to change:
Airdrop SVT, drop-able weapons are bad and they should be removed from the game not become more available.
The mechanism offers nothing in 1vs1 and creates all sort of problems in larger modes. The weapons have to be balances for units that cap pick them up and while it actually works as uncounterable MU transfer.
Lets for instance say that in a team of 2 player A goes PPsh and Player B SVT. Now player A can have access to PPsh/SVT conscripts with performance close to Assault guards while spending only half of his munition.
This mechanism is flawed in it core and should be simply removed from the game.
I completely disagree.
Droppable weapons allow weapon upgrade for multiple units without having to meddle with every single unit properties, therefore diminishing possibility of bugs.
Additionally, if brit weapon drops do not create any problems in team games that wouldn't be addressed already(dual LMG cons), then a much weaker weapon in form of SVT won't either.
As much as you hate them with passion, synergies between factions and commanders ENHANCE the team game experience, not ruin it.
I could bring multiple other examples and ask you why you were silent about balance about them, so lets go:
Ost buffing healing crates drop, it makes OKW infantry so batshit insanely OP its not even funny, everything from sturmpios to obers and all in between gets such massive boost that we have flashbacks from early OKW days. You're silent about these crates meant clearly for less potent ost infantries. You never had a problem with that.
Ost fuel drops kicking OKW teching speed into overdrive. Elaboration isn't need, we've seen 10 minutes King Tigers in team games. You never had a problem with that.
Literally OKW abilities and units being given to Ost through new commanders. You don't seem to have a problem with that.
Axis command units affecting allies while allies command units not doing the same. Again, you don't seem to have a problem with that.
Sorry, you can't scream that allied synergies are bad and be completely and utterly silent about axis synergies, so drop your hypocisy already and stop trying to invoke a storm in a glass of water.
