Logress's post only stated that we would get a 5 of 7 event later on that gives out complete Set 11 sets. It didn't actually say whether we keep our current ones or not.
BTW, I will be extremely pissed if our Set 11 actually gets taken away. It was our only compensation for the game suddenly going down for several months. And anyone who says the set should be taken away because the cards are broken has flawed logic. If the cards are broke, fix them. Simple.
Yes. Logress will take set 11 away from you after giving it out for free. He thinks it is a perfect way to bring back customers and build good-faith relationships between management and the playerbase.
