How am I over exaggerating? It removes a 320MP unit from the game for free and its guaranteed, like I have shown with the AT gun video for any other faction to do such a thing, it takes a lot of RNG and even more risk.
When someone that is very high rank with all factions agrees with me they both use it and have it used against them, so how can my opinion be based on "Because OKW have it"?
Slight correction:
It removes about 200 MP, the other MP have been lost before.
I think the probably biggest issue is that every OKW unit can salvage team weapons, which means that any team weapon lost for more than 10 seconds without support vs OKW is gone by either stealing or salvage. This is a very harsh punishment that basically no other faction do. This would suggest to limit the ability to Sturmpios only, but this would basically delete it from the game.
But all in all I don't think the problem is worth the effort of major rebalances. If necessary maybe add a few seconds or make the casting time depending on the model count as I suggested. The ability is far from making OKW very strong, which probably also lies in the Allied design that does not rely on static defense so much.
