Armor company as USF
Lightning or CAS commanders as Ostheer

If only the wc51 and M3 had a slightly survivability and pathing buff I would use much more the mechanized commander
If only the airdrop combat group wasn't so expensive (remove the ATgun) I would use much more the reco comander.

Incorrect comparison- for cost, USF armor is exactly as good as it should be armor / health wise, which is my point. USF doesn't suffer for lack of higher-tiered vehicles in the least (possibly in 3v3 and higher, but I never encountered problems even there while playing USF without EZ8 or Pershing).

You can also not build T4/Tiger as Ostheer and perfectly win a game vs any player. But you have the option.
As OKW, you can win with only Pz4 and Jpz4 (most players do) and not build panther or KT. But you have the option.
As USF, you simply didn't had the option till the commander with Pershing and still it is doctrinal.

Terrible comparison, since ambulance is infinitely more flexible than every other faction's healing (Base medics, medic bunkers, healing tommies, battlegroup HQ). It's also a bad comparison because you still bypass the ambulance until after LT / CPT and the light vehicle, which gives the early game strength that USF has in terms of MP spent on combat units.

More flexible, more wipeable and more expensive, Ostheer Sdfk and Sov M5 are infinitely more flexible (also look at speed stats) to reinforce on the field and dps, it is a matter of preference and the end: heal + reinforce on your territory or reinforce + transport and dps anywhere on the field, but saying the ambulance has no equivalence is a pure lie.
OKW is different but doesn't suffer anything on this point with a free medical truck + mp investment to make it forwarded point.

Seriously? The self-repair of USF tanks is the single best ability to augment the overall combat potential of vehicles in the game. I can't believe any logical player of any mode in COH2 will deny the immense strength of self repair.

Self-repair comes with lower armor power in general: lower armor values and lower pen values. Ostheer, till the recent Sherman buff, had better armors in all aspects. Not to say the Sherman buff has been done to respond the fact it comes around after the Ostheer Pz4. Now it is true Ostheer may lack something in this area.
OKW has a free repair station in addition to a boosted Pz4 and a boosted Panther, with the coming patch both coming at the same time you can field a sherman. Free Repair + better armor + better pen value opposed to self-repair. If it is balance for you, well we've nailed the root of the issue.

are 400MP I really don't think the LMG34 needs to be more than 60 munis.

So do Para and their LMG upgrade cost 120. If the LMG34 isn't at the para one level, at least 90-100 ammo cost seems to be fair. It delivers the dps equivalent of two BARs, 120 ammo

M5 comes at CP5, its a bit late to be that heart of a deathball blob. By that time counters are already on the field.

OKW and OStheer both have stock and doctrinal counters: mines, HMG42, Luch, HT and M5 counter: Pak, raken, Puma, shreck, faust.

Same, LMGs come at CP3, which is logically unlocked after stock Gren LMGs, as OKW you also unlock your doctrinal infantry before or around same time.

If around CP5 an USF player is still blobbing and winning, two reasons come to my mind: Or you are already on a huge backfoot from early game, or it is a l2P issue. And don't take this last comment wrongly, Blobs can always be countered with all factions and you just need more experience and learning to do it.

Probably a good commander to skip T1. I'm waiting to see the M5 cost but if it can reinforce in any territories, the commander may become meta and replace the infantry one in my roster (if I loot him).
