Absolute crap. Look at it this way.. lets say on your server you have 1 Tank, 1 healer and 10 DPS queued up. Now, lets add in cross server with say...10 servers. Now you have 10 Tanks, 10 Healers and 100 DPS AND you have the opportunity to be a total DB to Need on everything.
So please explain to me how this is better? Please don't spew the crap about "if you don't like it, don't use it". I could give you the same reply about the character creator.
