Thanks for all the replies. I appreciate all of them, truly, though they are all quite fundamental, which is partially my fault as I did say ANYTHING that differs from wotlk. I've been mucking around on the PTR quite a bit prior to this post so anything in regards to the dynamics of TBC as a whole is no mystery to me.
So I'm more interested in the details if you will. Something I came across recently was the flat 1% miss chance in PvP and the added lag. So more details that might be game breaking is what I'm interested in.
Again thanks to all who replied!
Cheers.
