if bf 1 was divided in 2 tech both 20 fu wich said granede up. and lmg up. would it change something ?
On the principle, it would as it now creates an economical decision making aspect which is now completely absent from ost: Do I want stronger infantry in early game, or do I want first tank faster?
However balance wise it would only matter if it was an extra cost compared to overall cost of unlocking ability to produce medium armor(like it is for literally all other factions, OKW being slightly different in a way that they unlock sustain and time efficiency instead with medics and repair pios for fuel).
Now, before you go into bunker mode like certain other individual, no one is saying its bad or it should not be like it is now.
This whole thread exists only because one person can not tell the difference between tech related unlocks and side upgrades as well as the difference between battlephases(or trucks in volks faust case) being a time lock for these tech related unlocks and not an additional cost to tech and nothing more.
