Not really a buff. Unless The combat package were to give pgren stgs to make up for the large firepower nerf in the early game. I only see this as a big nerf to okw early game. A sturmpio squad, despite hardly doing any mid range damage is essential for okw in the first 5 minutes. You can't just do without it.
I see what you mean but imo smoke and stun nades for 45 munis would be extremely useful for countering Maxim spam that plagues okw currently. This utility increase is worth sacrificing dps for the first 3 minutes imo, especially when you can still use spios and the Kubel to harass while volks dig in and defend.
I'm against the ops idea though, but I don't think it's a flat nerf unless you highly value the 4 MP44s early game. (Rightly so.)
(Not that it matters, but imo volks should get mp44s no upgrade, lose shrek and get minesweeping/healing field craft upgrade for 60 munis, and then get price increase. Then spios can be a long range kar98k elite engineer squad that can upgrade to double shrek.)
