Actual game design isn't agreeing with you. There are 3 factions that can wait with 0 fuel unit support till calls-in. and for the 4th one, it is only because they have no heavy capabilities...
i have no problem with sov holding out for 34/85, ost waiting out for tiger etc... it should be a valid tactic and once fuel upkeep gets implemented (IF), being able to stockpile fuel until the late coming first tank would be the strength of that strategy. like how picking sov industry after 3cp to have more manpower as long as possible is.
and i don't get how three armies having the ability to hold out for the heavy somehow disproves my point of inf+tank army >>> inf army.
people thought and still thinks holding out for a t34/85, is2 and tiger is so much better than going for stock tank units. and i see luvnest, stephennjf and other great players going for either t70 +t34 or pz4 even with doctrines with 34/85, is2, or tiger selected. and it works out great. what i am saying is that fuel upkeep has little to do with your "Actual game design isn't agreeing with you. There are 3 factions that can wait with 0 fuel unit support till calls-in. and for the 4th one, it is only because they have no heavy capabilities..." statement and your general stance.
what fuel upkeep is going to do is that it will prevent massing heavy tanks and the ability to replace them quickly. for example, i find i have about 300 fuel when tiger unlocks when i go no t3 as ostheer. i would be able to get up to second tiger pretty okish-ly. but after that, i would have like 14-16fu/min (my suggestion) penalty that makes getting more tigers or replacing that tiger. as of now, by the time you manage to pull a fast one and kill two tigers somehow, the tiger owner has more than enough fuel stored to quickly replace the losses. too many times i see a king tiger in a fucked up maps like trois point and what do i get for whittling down the OKW's infantry? another KT because i just freed up his popcap.
BUT I think why we are in disagreement. i see the problem as the ability to mass heavies and replace them quickly and
not the ability to wait out for heavies with low tier units. but you also see the latter as a problem, too. i think.
