Anyone who is honest with themselves knows that they're paying for extra retainers because they give them an advantage that is worth the money.

If you think that what you're getting from them is no big deal, then i guess you won't mind if from tomorrow extra retainers will only be used to make you tea when you log in, right ?
No extra inventory space, no extra ventures, no extra selling slots. Just tea.
Will you keep paying for extra retainers then ? No, because the advantage is not significant enough.

Now, we could argue that what is significant for one might be trivial for another, and that is very true. Some people might like their digital cup of tea every time they log in, and pay extra money for it after all ... Just like you guys like having extra inventory space, extra ventures, and extra selling slots.

I don't personally care about extra retainers for now, since i still have a bit of space, and i don't sell so many items (i wouldn't mind extra ventures though).
But i mean come one, just because it doesn't win you the game instantly doesn't mean it doesn't qualify as an advantage. Justifying it by saying "It's not actually winning me the game, so it can not be pay-to-win" is nothing but another hair-splitting argument, and everyone knows it.

The point of this thread is not to re-define what P2W means. It is to point out the fact that SE keeps implementing optional services that give more advantages IG to those who pay more money. You can label those services as "potato-to-walrus" if you'd like, it's not going to change their nature.
