You'd need to go through and remove all your RealID friends that you don't want on RealID anymore, and then tell them yourself to re-add you using your BattleTag. There's unfortunately no automated way to do this; and I don't really suspect there ever will be.
To be honest though, I wouldn't do this. I know if someone removed me from their RealID friends list I'd be a bit cranky. And there's not a whole lot of difference between a RealID friend and a BattleTag friend anyways.
What I'd do in your situation is to just use BattleTags going forward and leave your RealID list as is.
Is it worth it levelling a second toon that's the same class as your main? Does it generally help people learn to play the class better when leveling from 1-Max again.
For the vast majority of people I'm not sure that it helps very much. At the end of the day you do have a better idea of what's in the toolset of the class, but that only goes so far in WoW. I say that not because this game is easy at the heroic level of play or anything, but that the endgame itself is so vastly different than the leveling experience. It's often uttered, but entirely true; the real game starts when you hit 90.
What I think does help is leveling a class that's complimentary to your role. If your main is a druid healer, then level a resto shaman through dungeons. You'll find a new appreciation for the different strengths and weaknesses of your main class, and how other classes can help compliment those. This is extremely useful to know in raiding; you'll become not only an expert at your class, but the interdynamics of the entire role, and that's how you can elevate yourself to the next level.
Will Blizzard create Super servers for WoW by merging smaller realms together or all time zone realms together (all American east coast together and all west coast together)?
No. Blizzard's solution for low population servers is cross-realm zones. And while they may tweak the implementation of it a little bit, there won't be any merging in the future.
Could you please provide some info on flying costs and levels required for MoP?
2,500g at level 90.
I have 2 WoW accounts on my battle.net...account. One is long dead and unused, the other I currently have 6 85s on. My question is, the long dead account is a vanilla collector's edition. How do I combine them so I can get my mini Diablo and mini Zergling on my main account?
You'll need to re-up your dead account and log into it. That's the only way you're going to be able to get those awesome pets account wide. That said, I think it's easily worth the $15.
