I've opened over 2,000 packs, and yet my binder limit is 1,200. And this year, no consideration is shown for BND's, quite a few of which are clogging up my binder.
I have to make sure my Season Ticket Upgrade Tokens are tucked away in their respective players. I've quicksold my Breakouts Badges. I still have 153 collectibles, 75 of which are Legends Tokens, and more than 50 more are TotW/TotY Tokens. I've got a bunch of Rare Strategy items for which there is still no Epic Strategy Item set.
I've got 306 items with an OVR between 70-74, and another 224 with an OVR between 75-79.
With a few minutes of house cleaning, I'm down to 1,179 items, but 1,200 items in inventory in January is a crazy-low constraint.
