1. Slots2. A 3 or 8 hour shield to preserve my score at the end of an event3. 100 HP daily dealsThose are all guarantees for me. I emptied my entire HP stash last year for the roster slot sale even though I didn’t need slots. And I would do so again this year if they run the sale again (though my stash is only about 10k). Other than that, aside from a couple purchases here and there (buying out good small vaults for example) I don’t mind hoarding everything until anniversary. Those vaults are the best and I like turning them over as many times as possible. If we get lots of Tasky and Ham I’ll be glad I saved.
