why do we need more units that are non doctrinal we have the same amount of units as vcoh did, except germans had one more unit in vcoh then it does in coh2.
well even though both vcoh and coh2 has the same amount of units vcoh just seem to have a lot more options because of global upgrades like american barracks and whermacht veterancy, but i don't think it can work the same for coh2. adding more units into the game is kind of like adding more options therefore there would be more different play-styles to chose from.
i think there aren't many different kind ways to play in coh2. if we have more different kind of units in coh2 maybe we could see some people play more differently and have some unique play styles so things would look less repetitive.
you can say that doctrines extends different kind of play style but i don't see players being really creative in their doctrine use. since the doctrines are very simple and they only do a few things. there are only a few different kind of strategies you can go with each doctrine so there aren't many different ways you can use them, it's more like how long are you willing to wait to use this or that ability.
