I love US teching
When I play every other faction I have to commit to an opening. With US I don't have to worry about that and rifles are a solid enough unit to get me through any enemy opening.
USF is all about adapting. That's why it's important to try and read your opponent. T1 if your opponent goes heavy infantry and T2 if he is relying on vehicles or defense. If you mess up you can always get bars or zooks to balance it out. And no matter which way you tech you can always get out a decent light vehicle. And T3 has whatever type of armor you may need.
If you really want to spice it up with a different start then that's what the doctrines are for.
Any change would force too many light vehicles into one tech making that worthless since you will only buy one unit. Or make USF early game too strong. There is a reason rifles are slightly stronger then most basic infantry.
I always laugh when teammates ask me what I'm doing, because if I knew I wouldn't be playing USF correctly!
its not exactly just openings that should be considered. problem is when stuff like jadgpanzer, elefants and jadgtigers are in play. these things murder US armour. that is when you need hard AT that isnt jacksons.
considering zooks are horrendous. the next best AT is AT guns. now if you didnt choose airborne and hadnt gotten capt tech, that means AT guns need another 80 fuel. and to shell out 80 fuel at late game, that is really horrible.
thats when US tech is horrid.
