It's not pay for win but pay for diversity. It's a fair price for new units so stop crying.
Using commanders to add new units and features are pretty innovative and much more flexible than just buying a big expansion like SC:Heart of the swarm. HOTS only had a couple of new units for each race. If you only play multiplayer with one race its alot of money for just a few new units. Compare this to COH2 and the new units are pretty cheap and relic are not forcing anyone to pay for Case blue + ALL new multiplayer units like HOTS. Without these new commanders we would have to wait over a year for new units with one big expansion. With new commanders we might see some new units and/or features every 6 months or so.
It's pay for diversity since players can only use 3 commanders in a game. Yes, if we could use all commanders simultaneously that would be unfair.
