what you preffer does not dictate balance. the numbers themselves do. pios do more. pios cost more.
tell me, objectivly, if combat engies had increased line of sight, would they be better, worse or the same as they are now (no other changes, just increased sight). if CE could build bunkers, would they be better or worse? like i said, no "well buit" just yes or no.
Sandabags - they were given to pios because grens didn't get them. Ostheer got punished because cons and UKF infantry can build sandbags but grens can't. As a sort of comforting gift pioneers got this ability just to make sure it is more difficult for ost players to build them. Now you are saying that because grens can't get sandbags, their engineers should be more expensive!
Same with sight - there was a problem with mgs - they got nerfed because they were able to block most maps too easily. Pios were supposed to help them early game to make it possible for ost to survive and not get their mgs overrun as grens weren't able to capture or hold territory on their own. Instead of buffing grens or mgs they decided pios will have more vision to spot for them. Again, you want to punish the whole faction for those abilities they got instead of proper buffs somewhere else (for example, UKF mgs from tier 0 just got better vision and they don't need a spotter).
pios were given the ability to build sandbags years after not having them, for nothing (no accosiated nerf, just gifted the sandbags) thats not a nerf to the faction, thats a buff to teh faction. and regardless of how you think sandbags should be allocated, pios have them and it is part of their kit which is included in their cost.
No, it shouldn't. I'll give you an example of cons. They cost 240mp. They can build sandbags, they can oorah, they can throw flame nades, they can throw at nades, they can build tripwire mines expecially deadly to 4 men squads, they can merge allowing support weapons and e.g. engineers stay longer on the field, they can finally become 7 men and get a discount when reinforcing per model after they are 7. I'm not even trying to enumerate all the goodies they can get through doctrines.
Grens at the same time can only build a bunker (150mp - nonsense), have a nade, have a snare, can be upgraded with mgs.
If my maths is ok that is 8 very useful abilities to just 4 (one completely ridiculous - bunker). It probably means cons should be 60 manpower more expensive than grens using Your logic.
except it is part of their kit and thus part of the discussion with them. its something they can do and CE cannot. cons being able to merge is a conscript discussion and a trait that gets brought up when discussing cons as bunkers are for the units that can build them. you cant just decide what is and isnt relevant, thats not how this works. (i assume you mean reinforce and not heal, because outside a few commanders soviet do need to retreat to base to heal)
I wish balancing units was as simple as you say - unfortunately it isn't. I hope my example with cons shows on what kind of cherrypicking adventure you are. How can you suggest pios should be more expensive because of their abilities and at the same time not see so many Soviet units that get a lot of cool bonuses and abilities that are completely not reflected in their price!?
and i like how you are trying to discount bunkers as a faction feature but arguing against soviet russia being able to field a squad slight cheaper than its superior counterpart...
Because it would be enough if grens OR engineers build them - you can't spam them like soviet mines.
they DO MORE so theY COST MORE. you pay more, you get more. i dont know how you are not understanding this.
im even more confused as to how soviet have always had cheaper cons but now its destabilizing the late game, 6 years in. 30mp does not go that far. its a con and a half.
I explained it alread many times - lategame capping and repair advantage! Because you can just spam them to sidecap or recover vehicles for very little manpower. It was very visible in the last tournament. Soviets are the last army where you can say that if you get more you pay more. Remeber that their engineer capabilities to repair stuff, detect mines, lay mines are the same.
