Why would you pay tons of gold to other people to get rolls while you can solo this instance and get Ashes of Al'ar (if you're lucky). In this video you can see easy way to solo Kael'thas Sunstrider. I hope it helps to everyone who needed. Remember some people can go nuke 'em directly but this is safe tactic and can useable with any kinda gear.
