Guild Wars 2

Any special stuff besides achievements and the thing you can trade at the merchants(for hats socks and sweaters)?

I think we can get 1 more pet because we could not get all pets last year? (from this meta achivement we do to choose as reward)?

Any other special stuff? Worth doing tixx instance(not toypocalypse) again other than for that achievement where you have to kill toys? (which you also can get in open world I think)?

New mini (Ho-Ho Tron) isn’t from the meta, its from the giant presents you can open (that you get as rewards for minigames/escorting the yaks), or bought off TP.
But ya, you get a choice of last years minis from the meta. Which is useless to some of us, who bought the rest from Gemstore last year…

This isn’t strictly Wintersday, but another part of the release is The Nightmare Ends story instance in Kessex Hills. Doing the meta-achievement doesn’t have any unique rewards, but doing the story instance will get you the Antitoxin Injector Skin, which I think is pretty neat.

Ascended armor is new, although whether or not that interests you depends largely on how much time/effort you want to put into crafting ascended gear. There are some new, seasonal ascended back pieces as well, the recipes for which come from presents.

Edit: Oh, and two new titles if those interest you: Finders Keepers and Journeyman Toymaker.

Yes I now about the other meta from nightmare stuff. And about the mini. Other stuff from the gifts are those 2 ascended recipes for back items and then some endless or unbreakable stuff, right?

Unbreakable bell and some tonic. Are there different tonics or only 1 tonic? I think at tp is some gift tonic and toymaker tonic from last year? But one of them is at 250 gold so probably not possible to get from gifts and only the cheaper one at gifts?
