F2P is the worst payment model possible. Do not be deluded.
Of course, devs want to make the best possible game, and make the cash-shop stuff purely cosmetic, but after a while, greed kicks in. It always happens. First it’s small pushes, adding things that are beneficial to gameplay, but are either very minor, or can be obtained without paying. And then another push. And another.
Right now, there is not a single f2p mmo without p2w elements in it. And even if ToS won’t have any, are you sure that won’t change after few months? I have a hard time believing it.
Unless they put every single character customization element behind paywall, they WILL be short on money. That’s how it works, servers aren’t free, developers need to eat and pay their bills, and money doesn’t grow on trees. There is always hope that Korean, Indonesian, Brazilian, Filipino servers will get them enough money. No wait there isn’t, because they are begging to not be region-locked from International, because they don’t want to pay a penny to their regional overlords. But the harsh truth is, you can’t eat cake, and have it too.
So what’s the best course of action? Maybe don’t region-lock the countries mentioned above, but DO make the International server either pay2play or buy2play. Devs will get the money they NEED, and as an added bonus, there will be less kids and entitled cheapskates.
