x realms will change thing very very little (except for flamelash LLUUULL)
But I agree with u )
and want to add:
imagine playing within so massive pool of 50 k ppl 
just imagine.
No one will ever remember u, no matter how good or bad are u. U can afk in middle of BG for every bg untill naxx came out and no one will ever remember that.
U can solo pick and cap flag with 10 enemies on defense, u can be doing that constantly for months and years, spending 100 g cons per BG, it nothing matters, no one ever will salute u or recognize u, or /wing u for pre-maid.
u can even abuse and exploit, it matters nothing in the sea of 50 k ppl. its even worse on horde
I think u got the picture
This is longest post i ever made i dont do this, cuz writing of forums is stupid
