Im not really saying that zooks on RETs are OP I'm just saying how USFs don't really lose any AI power by getting more AT power. When you get Shreks on pgrens you lose half their DPS making them pretty bad vs infantry whereas USFs and UKFs don't have to put them on expensive infantry to gain some AT power. Just give them to your cheap sappers and RETs.
If we take away zooks/ piats from sappers and RETs then it force Allies to choose between more AT and less AI or more AI and no AT since it'll have to go on their mainline infantry
I'd say that giving RET zooks is comparable to giving pios a flame thrower. It takes a worthless squad and makes it meh at one thing and still worthless for everything else.
I do think along the lines of making a definite choice is good concerning; is this unit going to be ai or at. Pgrens really make you think because they're going to suck at killing infantry if you upgrade them. True enough, that's a much harder and more expensive decision than zooks on RETs. But, it's not exactly like people spam Rear Echelons.... At a certain point, ie every other unit, you do make the choice. Captain is a beast with bars now. So do I make a world killer or put zooks on him and make him crappy against infantry? Rifles are the same.
Wehrmacht is much more severely hindered when it comes to flexibility, but it has everything it needs in most every situation. I've found it much more important to anticipate what units i'll need when with wehr than usf.
The USF mortar is good, but it's not as good as the Wehrmacht mortar. Krupp stahl ja? The problem is in the matchup, as stated by aussie. A mortar is near useless against rifles for those USF players with a pulse. You have to have one to counter the USF mortar though, which hurts as it's manpower for a very limited use (which isn't fighting the damn rifles) and Wehrmacht just sucks on the move which makes the usf mortar seem better. It's team weapons vs no team weapons with plenty of ways to beat team weapons.
