29's are not the 19's and never will be. If you reread the original post, no mention of guilds or group queuing were ever made.
You're talking to two (me and luplis) of approximately 6 people who actually plays 29s in the present, who has played 29s constantly since MoP went live. There are nights where we're doing 3s or dungeons and we realize that we're the only people in the world playing 29s right now. There was a time when we were organizing a group of 30-40 people on a weekly basis to do 10v10/15v15 wargames in the gulch or AB.
We already have a difficult enough time getting 6 people interested in 3s. Most of the active players are either doing 19s, 24s, or playing on the private servers, and aren't interested in doing anything for 29s/39s on Live between now and WoD (hence the fact they aren't currently playing them). Seriously, you aren't going to just pick a server and fill it up with active 29s and call it the new 'home of the 29s.'
You're much better off just making/updating your toons on their home server, funding yourself, and then looking for others to play with when WoD comes out.
This is exactly the reason why NOW is the time to bring it back to life. It has never been easier to reroll a new toon a different server. BoAs are easily transferable. Gold is easily obtainable via selling pets on the new server. It has never been easier to set up shop on a new server.
There many, many things to do besides battlegrounds. You have to think outside of the box(remember hit will be gone). Now that we have crossrealm servers, it goes not have to be kept to one realm. As long as the community is in the same cross realm group you will be just fine. If you want to keep yourself isolated, then so be it. But keep your negative comments to yourself. Thanks!
Right now is the absolute worse time to try and decide to reroll to a new server. Sure, it might be easy with BoAs and pets you can throw on the AH for funding.
But there are no active 29s right now (besides us). You're literally asking people to reroll on an unknown server, with no guarantee of funding, community support, or even activity between now and WoD. What you're asking for is not only silly, but the exact thing most people don't want to be doing right now (especially twinks).
I mentioned 19s and what being centralized around a server has done to them because it's
relevant. Sure, Bleeding Hollow might be a great place to go to find a 19 guild, 19s gear, and community activity, but it's hell for anyone who isn't friends with the guilds already established there. It's a high pop server with lots of people group queuing into 19s, utilizing voice chat to roflstomp and GY farm groups of players who just randomly queue up for 19s.
Being organized is great, but only when it benefits everyone equally. Too many players in 19s/24s have an 'in group' mentality, excluding anyone who isn't their immediate friend, and these are the people who are going to be playing 29s come WoD.
Be smarter, think about what you're asking before you make posts like this.
