Since 2009 in WOTLK servers: Arena-Tournament, Blackrock, EXP on all classes around 2.2-2.6 rating. My favorite classes right now: mm hunter, shadow priest, disc, resto druid, mage. I'm sure you will find my streams as well as here as on my twitch-channel: www.twitch.tv/myravied
Twitch might have some extra saved streams, enjoy!
