Like, way more than I expected. A second skill bar (necessary in this game IMO), a credit cap of 350,000 (with the rest in escrow), extremely limited numbers of special commendations for buying new gear (each planet has its own commendation), and instant fleet travel. Character creation is limited to only TWO slots! That's even worse than I expected. Race options are limited. Character Legacy options are limited.
You know the one thing that really pisses me off about this, though? I don't care that a ton of convenience and cosmetic things are behind a paywall. What really gets me is that there is no way to trade in-game money for the micro-transaction currency. If that was an option (like in GW2), I'd be fine with all of this.
