I am guessing you bought the Arcane one and are disappointed with the deal you got. But if you check the aa boost from it, it is still way better than the mythic one. Your qualm shouldnt be against the boost but rather the price of it, which btw STS doesnt decide, the players do. Arc were was I believe 50-60m first day? And it did drop, so people who bought on first day or first few hours should have more reasons to complain about. People made the choice between mythic and arc, which one they would like to have within the last week; boosting it now would mean you cheated them. Further it is already a very OP aa, giving it more would mean it has potential to break game.
