If you're on alliance if you type /who you can see who you're facing against on an arena, and you can also dodge queues by adding them on your friend list.
Not that I do that, since I know no one worthy to do so.
Translation(according to google translate and some adaptions that I made from google translate):
He put a sky golem for 999k gold in the auction house and when it was bought he only received 90k, so he requests the remaining 900k.
I know you're trolling but lets say someone read this and don't get the concept:
The other team didn't enter the arena so you can also notice that they got +0 rate.
I wouldn't be reporting this insult if it weren't a very specific situation since I really don't mind them.
Realm - Pandawow Fun
Player - Childboyz
Description - He insulted me after losing an arena.
Proof - Image one and image two.
Comments - He is pretty salty and rude to most people that I've seen him interacting with, and also lagged twice during the match.
