1. Rifleman upgrades are not just MU, it's also MP and FU to unlock.
2. ...also should cost much more than what exactly?
3. Doctrinal units don't have to be a straight up better version of standard units.
Please, compose a full argument so I can give you a thorough response.
PFs have attractive abilities like panzerfaust from the start, which helps your army not to get bullied by the M3 with flame thrower CE inside. The weapon upgrade is strong and squad being 6-men with increased sight allows you to spot MGs and make good decisions before and during engagement. If you don't find such features appealing then you don't have to use this unit.
i will explain my full argument:
1 we don't increase the base cost of an unit cuase of it's upgrades, we increase the upgrade cost
2 the upgrades are priced fairly, the shreck make us lose at nades and pfusi g 43 is a mix of cons upgrade and g 43 upgrade (the g 43 are still worse tho than normal)
3 the unit itself deals worst damage than volks and cost more, i could understand if they were better or costed similar but both worse and more expensive does not make sense
they either need to : reduce the cost in mp as they don't perform for the price or a better base weapon to make them perform for their price
the argument that they have better scalling or they have versatile upgrade is worthless as we have unit with great vet and versatility that don't pay for it by being overpriced, and they are not even doctrinal
let's not forget u don't pay for nades and upgrades unlock for doctrinal units (and even then pfusi upgrade are locked behind tech)
the simple comparison is rifle, both have great vet and versatility, but one actually perform for its price while the other does not, and before u say "rifle pay for nades and upgrades", yes they do and pfusi are doctrinal and have draw backs (no at nades with shreck , unlike zook, no 6 g43, unlike bar)
so again why should pfusi cost more and be worse ?
btw pfusi vet is almost the same as penal
