I and my reals are looking for a good high populated PVP server(Not with a queue) with a good 10 man raid population, if any suggestions could be made that would be great.
Well Outland is amazing Realm, but sadly bussiest of EU, and has a Que everyday.
Try to look at Realmlist when it's night (20.00 - 24.00) Those times the realms are most busy at EU.
And then take look which Realm isn't that full and can forfill with your requirements.
EU ~ Outland
You could take a look here http://wow.realmpop.com/eu.html
I will say anything about how accurate it is though.
