Will someone explain me the Vanilla PVP system?

My real question here is… how does ranking work on the clusters? Is it per server or per cluster?

I’d imagine it’s per server. Only having one Rank-14 each week per cluster would be nutty on some of the larger clusters:

Ok seems good either way.

It’s per cluster. The only exceptions to this are the RP realms which never were connected to begin with. While ranking calculations are restricted to cluster, all Classic Era Realms of a geographic region (North America) are in the same queue pool for BGs.

OK, that’s kinda what I thought.
