XMogs are fine. You already changed 1800 / weapons transmogs. They are something to work hard for considering most of blackrock is at least 2k molten/retail level.
I don't hear anyone complaining that xmogs are too boring.. maybe a lack of weapons.. but what people are misreading is that it's going to be like when you unlocked brutal gladiator and suddenly half the server had it.
Do you remember when you changed seasonal arena gear back to high rating? A lot of people were upset. At least leave arena season gear alone? I'm worried that I worked hard for a thousand games to earn my s1/s2 and every random in warsong gulch will suddenly have it.

And...If you HAD to lock namechanges, fine, but realize that it's going to be another issue of r1 sniping and soloqueue drama like it was on the old server.
