Guild Wars 2

I completely forget, upon finishing 10 achievements for the WvW Sprint Tournament, did we receive some kind of locked chest or anything, that would become unlocked upon tournament’s completion? If so, I need to look through all my bank tabs/character’s bags…

No, the chest is handed out after completion of the tournament rather than completion of the meta. It should be available to you now.

Ok, i got the chest, but now as wiki says following:-

Take this ticket to a WvW weapons specialist.

— In-game description

WvW Tournament Claim Tickets are rewards to the players that completed the WvW Spring Tournament 2014 meta-achievement release. They can be used in exchange for weapon skins at the Battle Historian.

Now, on EB, I went to Battle Historian .. thats not a shop but just npc giving info about the tournament and rankings etc

So I went to weapon specialist ??? .. i could not find npc by that name .. battle master only offers gift of battle and I dont want to click next to see if he opens a menu .. because if he doesnt, i will lose 500 badges for no good reason and i will get a gift of battle which is utterly useless for me.

so where is the npc where i can spend my 500 wvw reward tickets?

Google and wiki are your best friends. NPC will be available on June 3rd, after the possible patch. So keep the tickets.
