Again the decision for RNG LMG was a band aid and it proved to be a bad decision I am not a liberty to say more.
Since: "you agree with the fact that high dps LMG is problematic on high model count." I have little more to add.
That would need a larger change, not only for Osttruppen. I like the idea behind your critics, maybe someone makes a small mod to show the results.
But, mainly I want to buff Osttruppen. Not primary to make the unit better in fighting. E.g. Osttruppen reserve would be improved a lot if they could build sand-bags and wire.
If Osttruppen get sandbags + wire with first tech, all other commanders with Osttruppen would get a benefit. Simply to make the ability a litte bit more attractive.
Making trench (only in Osttruppen-Commander) and hull-down (only 2 other commanders) one ability, it would be a huge improvement for all these commanders.
Edit: My air-dorp critic is, that it is overpriced for what it can. You only need it one time, giving you 10fuel and a litte bit mun. A PaK40 and a MG34. That for 450mp.
In best situation you have 1 Osttrupp (200 mp) -> you use the ability (450 mp) -> now crew them and fill refresh the Osttrupp and make the weapon-crew be 4 men (8*16 mp = 128mp). That are 778mp needed for one HMG34 and a PaK40.
-> If you build T2 for any reason, you can build a PaK (320 mp) and a better HMG42 (260 mp) for 580 mp. The air-drop gives you a litte bit fuel, lets say ~ the price for T2.
SO, where is the air-drop a benefit?
Simply change it back to old 200mp for fuel or mun, or change it with a Beute-T34 with skirts for 90-100 fuel. So you can scip T3. Mybe build-able in HQ like new Panzer 4.
