Yup... my character has also been copied to the testing realm... just hope its over. Last when I checked, it was 29 days waiting time, so unless you did yours long ago, it might not be there yet
As for pre-tbc / pre Wotlk raiding... I dunno, I have a total different feeling towards what happened with hunters over the years.
I would'nt say we were ever a face rolling class pre TBC, but I only say that because back in the old days, it was harder playing a hunter than it is today.
You could NEVER p0wn the DPS meters, unless you had really sucky people in your raid. Hunter DPS was just not there. (This is MC / BWL / AQ days )

Those were the era's the fire spec mages crushed anything on the meters.
Also way back then, hunters were the raid's main pullers. And this was done without MD's, even pet pulls in AQ40. You were forced to know how to kite mobs, this is no longer needed today. Also things like BWL supression room pulls, omg those were painful. One bad pull, raid wipe, and we are not talking 10 man wipe... 40 man wipe. Nooooo pressure ! hehe.
Personally I feel they made the class easier to play over the years, but they increased the theoretical knowledge required to perform at peak levels. You had to know what shot clipping is, you had to know what macro's worked and which of them did'nt (famous !autoshot comes to mind )
Unfortunately it also resulted in completely clueless people just copying other people's macro's and then p0wning the dps meters with little guidance. They just knew... hammer this macro, and gem / enchant your gear as follow. Thats where the whole facerolling thing came in. How many hunters never updated their macro's when the syntax changed in macro's ?
Nowdays the tanks just charge in and pull, there is no longer a requirement for tricky pulling shots from hunters.
**edit - As for the survival dps thing... yes, I am very concerned how they are changing the trees again. As Werries stated, I also have a feeling the MM build will be superior, unless the black arrow shot is really very good. But then again, its waaaaaay to early to speculate, there will most likely be another 20 changes before uldar goes live.
