First of all, I wanted to apologize that it took me so long to respond to these but never late than never, I suppose:
Well the expansion comes out 8/30, so it's up to you if you want to jump in now to get a feel for things just as they're all about to change. The new patch comes out next month though (at least that's the rumor), so that might be a better time I think. Unless you can't wait because the ITCH is too strong. I might be down to play an ally character too though, if you want company.
I just started my character today! I decided to play yesterday because I just wanted to get into it as soon as possible. I started a human mage on Stormrage, so if you would like to join up, I would be down with that!
I've been happy with Whisperwind alliance. Been on it since launch. Not a huge server, but not dead. Always felt like the right size. It also merged with Dentarg which means both realms count as one server, including same AH, toons etc. Basically I can have twice as many toons on the same shared server.
I looked at Whisperwind, and the fact that you can have twice as many toons is awesoke, but I heard so many good things about Stormrage on Alliance side that I wanted to give it a try.
in like 2 to 3 weeks the pre patch will hit and most classes will change, i would suggest waiting for legion or that patch to get a feel for things really.
my server sargeras is pretty solid as an east coast ally server, same for stormrage, both overly populated etc.
Yeah, Sargeras, Whisperwind, and Stormrage were my top three but I went with Stormrage. I wish there was more or less an official GAF server like Guild Wars 2, but I can always transfer my character to a different server if need be.
Thank you all to the responses. I appreciate it and I'm sorry I forgot to respond until just now. =P
