Considering that you get 2k points for a victory (as shown in the screenshot) I think the prices are kinda fair. A new commander every 6th game...
The only think they should change is that duplicate commanders give more currency than duplicate bulletins
I haven't played the Beta, but the Alpha, were the points meant only the time until your next war spoil drop.
You cannot get any "currency" in other ways than salvaging double bulletins/commanders/skins.
(In the Alpha)
So yeah. That sucked. Nice to be able to talk about it now.
The new system is bad. You can't reliably accumulate points by playing games, you still have to "hope" for duplicates. This is simply stupid.
(Please remember that everything I wrote is based on my Alpha experiences, not Beta.)
