But imo one should probably tone down the performance if it comes available early. For it cost and timing it has much better armor than the 221 that come about the same while its high mobility and range of 40 makes it very good at kiting. It can even attack and force retreat on unvetted HMG from max range easily. Generally it is really hard to counter without a vehicle.
Imo one should consider lowering the unvetted performance with range to 35 and lowering armor to around 5 and move smoke to veterancy. If there is a need the vetted performance could remain the same.
Imo one should also consider removing the crew from these cheap USF units like WC51 and possibly the M20 since the value of crew allow cover most of the cost of the unit.
I would also suggest to make the 221 available to Ostheer to act as a soft counter to sniper/light vehicles and the 222 come later with higher power level. This change would help allot with timing and performance of light vehicles.
What a great ideas!
Then we can move on to buffing grenadiers by slightly toning down their performance by removing their LMG, breaking their legs, making faust require T4 and rifle nade be 70 muni, because it is too oppressive against vet0 maxims, we could then slightly increase cost of medkits, maybe even leave vet unchanged and we then could decrease the cost to 220 and decrease their build time by 5 seconds, now grens are buffed and balanced against everything.
