The link with JQ seems to have revived WvW in AR, unlike the link with YB, who totally ignored them.
Funny you should say that as I faced similar experience in the last linkup with YB. Either they ignored you or they say nasty things as though we were responsible for their being linked together with AR. On the other hand linking with JQ has been a good experience so far despite my initial misgivings. I find their community friendly and cooperative.
