Special: I have the quest on NA, not on EU => you should have it on EU and be willing to receive the quest from me on NA (i.e., NA should be your main server). In case you are interested in cross-server trading in general:
If you are interested but *don't* have the quest right now, feel free to add me nonetheless if you want to start a cross-server trade relationship. I was scammed once, so I won't gift away my quest like that, but if you are willing to undergo some risk (on your secondary account) and offer me the quest at some later point without expecting payback right away: I will pay back my debts. I already have one such trading partner, but she's so rarely on EU that she owes me 2 packs now already, that's why I try to open new possibilities :D)
If you play primarily on NA, but also on EU, then maybe you are interested in cross-server trading? Whenever I get the 80g quest on NA I would love to give it away and get it on EU in return. If you'd like a long-lasting trade routine, drop me a message here on hearthpwn!
