What is wrong with Warmane WOTLK servers???

Hello, 2 minutes ago i qued for solo que, i went in the kitchen to grab a water, i came back like after 30 seconds, i was disconnected from the server when net is fine, i logged back in i got deserter and lost -20 rating from solo que.

This is the third time that happened to me in less than a month.

I also get random freezes in arena losing games where should have been won.

Can you guys please fix your bug that when you dc you and you are in que for arena you auto remove que and not get deserter?

Its really frustrating to get rating like this.

I am not even in top 10 anymore because of this.

Regards.
