Awwww, S4 Leaguers are being thanked for their support! How adorable! Let's see...
O-Oh... I guess players who simply play this game aren't considered supporters? As if the people who throw money at this broken game is the only thing keeping this game alive?
No matter how you look at it, that's not true, and that's the biggest mistake these people (whoever is in charge) are making.
But anyways, winter and gratitude... I see...
I mean, if they had mentioned something about Christmas it would make relatively more sense... But they didn't, and that's what's so hilarious about this.
But hey, maybe this could indicate a future event where players get a chance to win those listed rewards above (or anything similar), and the reason why this promotion "thank-you gift" only lasts for a very short amount of time (this event started 4/12/15) is to persuade people to spend money (for those who are able to). It seems to be a common method that happens in this game, anyways.
