Not knowing all the details behind it, i used it for my 3rd prestige with the hopes that it would let me reallocate my permanent token unlocks [which is currently M8 and Ghost....and now SMR]. Since the UAV nerf i don't feel i need it as much and wanted to unlock the Chicom [my fav smg]. It didn't go as planned. Actually idk what happened. I still had ghost\m8 and extra perma token [smr]. Maybe i had a few more level tokens, IDK. I got to lvl 10 this morn in about 2 games [still x2 xp]. Seems like a total waste. Would have preferred another extra slot.
