Largest realm as of now?

No one has the addon on Ursin.

That's not what the addon says.

Oh god, why would you ever play on Scilla?

Can anyone suggest a good F2P realm hosted in the LA datacenter? Been having lag problems lately and wanted to try a different battlegroup.

I think most are in the LA center, I know Aerie Peak is, Vashj is, and I believe Misha is. I can't speak for other common ones that I haven't played on though. Are you looking for Alliance or Horde, PVP server or non-PVP server?

EDIT: Yikes, apparently forget everything I just said. I looked it up for you, my info above is wrong. Here's a complete list by datacenter:

US realm list by datacenter - Wowpedia - Your wiki guide to the World of Warcraft

2nd edit: Given that list, I would say Feathermoon, Eldre'Thalas, or Rexxar (now merged with Misha) would be good choices where there are other F2Ps.

Thanks, I'll check them out. Interesting that Rexxar (LA/CT) and Misha (Phoenix/PT) have merged - I wonder how up-to-date US realm list by datacenter is?
