1. Not a different conversation. Especially that people against making pios more competitive or cheaper keep suggesting they do more and thus should be more expensive than CEs. The same people don't see that echelons and sappers can be much more deadly lategame and cost as much as pios. Mainline infantry, especially conscripts, often have more abilities and it is not always/almost never reflected in the price.
2. Vet requirements won't do the trick imo although they are unjustly higher for pios than fro CEs. It won't be enough. The goal would be either to make pios as useful as, say, sappers OR make them simply cheaper to be more disposable and more easily replaced when lost. I like the latter solution better as ost can really be completely outplayed if they can't replace their engineers. It is especially visible against USF - because of crews. But also against Soviets to a lesser but significant degree - due to cheaper cost of replacing and reinforcing CEs on top of many other non stock repair abilities.
So usf and ukf spending recourses unlocking just the racks to able able to put upgrades at about 80 to 90 muni to put double upgrades on their engineers, dont add up to their cost? Ukf lacking cqc entirely outside sappers and them not being in t0 does not allow them to have good dps at closer ranges?
Cons have more utility far more utility then grens. And they do cost more then grens to get them fully kitted out. People tend to forget cons need a squads worth of mp and fuel to unlock a crappy nade and snare just for them and not gives extra units.
Even the weaker maxim is more expensive then the mg42 considering you need to tech to it.
You play all faction you say? Then why leave out addional costs like these? Must an primarely axis player me thinks. And yes i primarely play allies but i at least try to be as objectivly as i possibly can.
