Pick any of the BG9 servers to roll on though, other than grouping/guilds and AH economy, the PvP will be the same on all.

If your from EU or US I'd roll Tich or Blackrock, probably lean more towards Tich. Blackrock is combination AU/US/NZ. The rest of BG9 make up mostly Oceanic Realms - amusing that with the worst latency and the most Australians in one place we have the biggest most competitive battlegroup - yet nobody will give us AU servers.

If you are going horde, hopefully I see you around once I get my new team levelled up.

While they are a poor combination for PvP - we'll see how we go... having loads of fun levelling them.
