What is this fallback hopper you speak of? I also bought the Le edition and i used to be able to see all of the other classes but once i hit 50 i was only eligible to play wetwork and operator. I tried to enter my code in for the map packs and specializations but it says it has already redemeed and i can't remember if i did or not, do i have to wait till the 30th to use this code or can some one help me out :S ? also does anyone know if i do not pick a specialization and say i hit level 70 can i just back log that expierance and level 2 classes instantly once i get the ones i want?
