So i went to Deathwing realm cuze Lordaeron was down, and on Deathwing i have 80 lvl mage and 20 lvl paladin. I can see my paladin but i can't se my mage. It's like don't even have mage on that realm . Here are come pics http://prntscr.com/ayztschttp://prntscr.com/ayztxr
if it's not showing in the character list then either you or someone with access to your account deleted it. check the restore character area of the website and see if it shows up there.
Noone has access to my account except me and i'm not stupid to delete my character, and it's showing that i have 2 charasters on realm but when i enter i can't see my second character(mage). I was on restore character but my mage is not there which proves that i didn't deleted it. It's seems like he just bugged somehow.
