I was going to make a poll, but couldn't fit everything into ten choices. Crafting materials, boosters, gathering tools, dyes, non-Ascended boxes, mystic forge stuff, minipets, tonics, ascended rings, ascended amulets, infusions, WvW plans, and crafting starter kits, oh my. Plus the standard bacon/pie/iguana option, of course.
In case you've forgotten what you can get, here's a list of laurel stuffs.
For my own part, I was originally thinking of the non-Ascended boxes. I still have many characters that are running around in rare armor, and I'd like to upgrade them to exotic. But I definitely want level 80 exotics for them -- so the chance of getting level 78 or 79 or even 80 rares is not very enticing. I have no use for the mystic forge stuff, don't like the way minis are implemented currently, so... it's looking like Ascended gear. Though that's not really necessary given that I don't run fractals. And that's a whole lot of dailies for all of my bazillion characters. Hrm.
