I'm not sure what question you are asking Sluzbenik.
The new OKW and US forces commanders; commanders like Rifle Company, Mechanized Company, Fortification Doctrine, Scavenge Doctrine, etc. are not for sale currently.
Will the commanders who are on rotation go on sale? Each rotation? I have no idea. We'll have to see.
edit:
It's interesting to me that they say that the "Free Commander Rotation" is temporary. Are they referring to the current rotation? Are they referring to the entire system? Will they rotate commanders for a few months and then shut the entire thing down? I must admit I am a little confused about this new feature.
^ THIS is the inherent problem.
If the ONLY way to get game changing mechanics (Commanders) is by PURE luck - the system is broken.
You can't BUY them - you can't TRADE for them - you can't EARN them.
Basically one could buy this game and NEVER have a certain commander even if they were willing to sell a kidney to pay for it - it's ALL RNG.
The temporary Commander rotation does nothing to address it - it may even make the problem worse in that it provides players a temporary opportunity to a commander that's ONLY accessible via RNG - so to let them play it for a week - then leave a bitter taste when its taken away AND the ONLY way to get that Commander is by PURE LUCK - it'd just end in disappointment.
If people here on the "Relic can do no wrong and you're all a bunch of ungrateful/L2P noobs" band wagon can't see that's a broken system - there's no point discussing it any further.
War spoils based on RNG grinding should be limited to cosmetics.
Commanders should be rank locked or purchasable.
Duplicates should be tradeable.
EVERYBODY wins.
