Why do guys think the price should be increased?
I don't think the Ostwind's price is even relevant.
The problem is you no longer need to build T2 if you're not using the Ostheer lights. Panzergrenadiers have your anti-light AT duties covered.
Previously, if you chose
not to build a 222/251, you'd save yourself 200 MP 30 FU.
Now, if you choose not to build a 222, you save yourself 400 MP 50 FU.
Opening up this T2 skipping route hugely increases the opportunity cost of Ostheer's T2 units.
