I told my best friend on Spiral Knights that I'm pay-to-play and now he doesn't trust me anymore, so is there anything wrong with that?
Pay-to-players are the ones who bought crystal energy to put it in the market for free-to-players so I don't see an issue if that helped them.
IMO, there's nothing wrong with Pay to Play players.
People have issues with them because some think it's almost like cheating; you're buying an advantage etc.
Me, I have no issue. Unless asid player is a total idiot and rubbing in my face the hordes of CE and cr he has as well as all his '1337' gear while calling me a noob, and/or completely sucking at the game and/or blaming it all on lag or something. Then it annoys me.
Otherwise, nurp.
