@ austerlitz and RMMLz, Yeah I feel ya's on where your coming from, the MG42 starts off lackluster due to a poor traverse speed and then jumps in performance at vet 2. Where for example, the Maxim starts off good and pretty much continues in the same vein. The MG42 with vet is better imo, but the Maxim is better at vet 0.
Personally think the MG42 could be tweaked to be a bit better from the start, but gain a bit less then it currently does with vet.
Alternatively, just make it so suppressed units can't throw nades for all factions. Would help allot and remove a bit of daftness from the game imo (crawl into nade range!)
Pgrens are good for their manpower cost, but will vary in effectiveness depending on the map/situation. I like that design tbh, unlike LMG grens/Obers/LMG paras, they require a bit more thought. Pity the new factions weren't designed with a similar mindset.
Scout car is a bitch to micro, turns like a truck and the acceleration rate is a bit meh for a glass cannon. Fix that and it'll be grand imo. Currently it is usable, but micro intensive and annoying.
I believe Ostheer get a discount on their LMG/Rifle nades as the tech is effectively built into the cost of tier one. But your paying for it in one lump sum effectively in the early game, which delays the t1 units and is a big investment in tech that you require munitions to use, which in the early game for Ostheer, is a bit light on the ground due to less map control and Ostheer requiring munitions for healing etc.
I prefer my original solution then a complete overhaul of the above, as I think incremental changes are easier to implement and judge. You have to consider, if you break it down so Ostheer can tech the LMG/Rifle nade etc individually, then t1 will cost less and Pgrens/scout cars/Pak will come much faster, which will present new balance considerations/challenges.
In regard to normal tech beyond t1, yeah, t4 is too expensive currently, again I like the common suggestion of adjusting the tech costs, so they are similar, but the buildings cost more and the tier tech less, so skipping a tier beyond t1 saves more resources.
But I feel that is another topic as Soviet tech would have to be adjusted at the same time
