With usf you go one or the other route you dont have all the units at your disposal unless you backtech or get doctrines unlike ost.
Right the balance team basically removed any disadvantages/drawbacks/risk involved with parallel teching for every single faction so that's not even worth considering.
Just try not to tech as soviets and get the 7th man. You cant cant. Cp slowly gains over time and costs nothing you will get vsl regardless of tech. It unrealistic i know but to say t4 requirement means nothing is just wrong.
Yes of course don't play the game at all what a realistic statement. May I remind you you need to actually build t1(the same thing as teching for sovs) to get grens at all in the first place. Just try not to tech/place buiding and get 5 man grens, You can't OMG what an insight.
T4 tech requirements mean nothing as you get it eventually. After that how do you justify less costly unit out performing another. Because the games gonna reach a point where every player has access to all tech and only resources will be spent on unit and upgrades. What justification does tech requirement have then of less costly units out performing more costly one. There isn't any other wise OST t4 units would be priced lower Since they come later than all other vehicles but that wouldn't make sense in end game(or even post tech game)
