Considering that getting an OKW like rework is impossible, you think that shuffling units from tiers wouldn't work at all because one would be the defacto tier to choose from?
If i'm not missing the point, i think we are just gonna discuss whether keeping the current model with "stand alone" officers but with an easier access to both versus a straight linear tech is better.
Considering USF reword is impossible, I would rather keep the actual tiering model and play with unit stats and cost.
Like
-Vet0 RM could receive native better RA at cost of lower RA reduction at vet3. Give Riflemen 0.87 native RA and maybe (need some test) people would stop rushing them or trying to outspam them with 4grens or 4volks start.
-Ambulance fuel cost could be removed and manpower cost reduce
-HMG.50 receive a wider cone of fire now that sprint is removed.
-M1ATG having also a wider cone of fire so less flankable
-M15 having native 360 health points so it survives 2 shots
-BAR could cost 50 munitions instead of 60
I mean, if we decide to not touch the teching structure, there are things that can be done without destroying the balance.
