Hey,
Just wanted to tell you guys that on EU servers the honor doesnt seem to have converted to gold yet, so you can buy the full 371 gear if you have a lot of honor from the arena points to honor points conversion, like me(had 18,3k honor when I logged on today which I got from my old 10k+ conquest points).
As of what I've heard the horde pvp vendor doesn't work yet though, but the alliance one seems to work.
This is pretty common sense, but for those people who haven't figured this out yet, go buy the 371 gear with honor before it converts to gold!
