I seriously considered writing a guide to this event, I actually did the whole chain up to Champion status and took a couple of pages of notes to document the progression while the Test Realm was up. Then the WoWInsider folks said they were writing a guide and shortly after that I found an excellent walk-thru already available at Banana Shoulders**. There's also an article on WoWWiki for folks who prefer a more outline-oriented format instead of the walk-thru version. So instead of a tourney guide... I wrote one for Noblegarden :)
There's just one thing I wanted to add to the abundant tourney information that's available elsewhere. When I logged my level 77 hunter in tonight, I had an email from Justicar Whatserface. I thought this was kinda weird, but I couldn't imagine why I would receive an email if I was too low. Since I'm still working on my level 74 Gorilladin and level 75 Kitty, I haven't done much adventuring in Storm Peaks or Ice Crown yet. I've been finishing up Sholazar and Grizzly Hills to try to get my pets a bit more experienced before moving up the food chain. But I'm a curious type, so I flew on up to the new area to see if the quests were really available.
When I got there, they were unlocked for me! At first I thought I'd just pick up the quests from the Blastbolt Brothers since they seemed pretty easy. But when I went into the Silver Covenant tent they welcomed me with open arms and gave me their dailies! I actually tried the Edge of Winter to see how hard it was and my 74 'rilla killed Lord Everblaze just fine with mend pet. So it seems that as long as you can fly - you can joust!! As far as I'm concerned, this is a great way to get XP and start collecting tokens so you can buy neato gear as soon as you reach level 80. Woot!!
Or as the fella who watched me free the maiden from her icy prison said:
"Well I'll be damned!"
**I know that the Banana Shoulders site may not be working when you visit, but the guide is so well done I wanted to share the link anyway. Especially if you're a visual type, there are lots of screen shots mixed into the guide to depict exactly what you have to do. So if you're having any trouble at all figuring out the Tourney, this guide is where I'd start :)
