Random vs Choice Packs

Dear Developers,

Why in the world do you have trade in based events with random rewards vs Choice packs ?? It's idiotic on your part to essentially punish players of your game this way. I have 2 Next Gen players and traded in the 3 80s to get another only for it to be one of the ones I already have. Since they are untradeable he is useless until I can acquire more cards to trade him in for the 84. I try again with 3 more 80s. Get the same freakin guy. So 2 of my 4 NG players are unplayable. Thanks. I have to use the auction house and use coins I didn't want to to acquire enough 80s to try again. 3rd trade in I get the other of the 2 I had originally. So in 5 guys I have 2 I can play. If they were Choice packs id at least be able to choose players I dont have. So you're either the dumbest smart developers in the business or you just don't care about the player base ?? Id hope you'd correct this at some point but since you are the only game in town, you'll likely do nothing.
