You have a point there, but would anyone use that much?? And unless you are a commentator, there isn't a use for that much amount of theather slots, either.
Even with the classes i have now, i am already quite satisfied with it. These microtranscation deals are to scam our money. We must not fall into their witless trap.
Even at the least, the camos personalization packs were at least better that the slots expansion deals. And note that they even cost more than 160 microsoft points (US $2)..
Think again.
