I've just seen what's hands down the most fucking impressive thing I've ever personally seen in WoW.
So I was doing some Arenas with a Hunter, just some random guy. We finished up and I still had loads to go till my cap so I went looking for another guy. Came across a Frost Death Knight which I was happy about since they're very strong imo. We did two games, won 1 lost 1, then came up against a Mistweaver Monk and Affliction Warlock. We nuked the lock but they managed to get me down in about a minute or two. This Death Knight then went on to survive solo for about 15 minutes, nearly killing the monk a couple of times and eventually when the clock hit 4 minutes left managed to down the Monk and then the Warlock leaving us with the win. I was fucking blown away.
Here's his profile
Thank you based Gauldur, you're the hero we need.
