I'm in the same boat as you. I was very very lucky to get my horse after 9 keys, I probably wont be that lucky again. Maybe I'll send in a heartfelt support ticket before they do the rollback and maybe they'll make an exception for a few people. After all, this isn't EA Support so we might get lucky.
This sucks. I bought 10 dollars worth of keys and I got a nightmare horse on the last one... I probably wont get that lucky again if they do any sort of wipe
