Nah, this is just nonsense. As has been said, there is no element of belief or faith in World of Warcraft. Community, ethics, culture and emotion now - while these are things you would expect to find within religion, the same could easily be said within any other sufficiently civilised social grouping. That alone doesn't form a religion.
Also, have to comment on this:
Have certainly never had anything close to a religious experience while playing WoW anyway...
Also, have to comment on this:
Afraid I just can't buy that. For those who follow a particular faith, then it is highly improbable that they view their beliefs as "illusion and fiction". One of the main facets of religion after all is believing something to be true, regardless of whether there is little or no actual proof of it. If I was looking for illusion and fiction, I suppose I could go read a work of fiction (surprisingly enough).Though a virtual space like WoW is ultimately not real, Zijderveld would say that that very fact makes it even more like a religion. Religion is based in illusions and fictions, but the important part is that even though people may know it's not real, they experience it that way.
