I forgot to say about the arsenals thing... And I think it is very important. Arma is a milsim. Supply depot should be the better option to stock supplies.
There is something very off about walking into a base and seeing 10 arsenals for storage. It's an optimal strategy since 1.7 with the supply depot that can be destroyed.
Also if the supply depots are close to each other its start a chain reaction and every supply depots just explodes.
It's very cinematic (reminds me of squad a little) but it should not encourage player to just ditch them completly.
