I know I've read this over the past couple days, but darned if I can't find the reference now. But I'm gonna press forward and tell everybody what to do anyway. lol.
For those that have paid attention to the PTR or the patch notes or any Wow reporting site lately, you'll know that there's a new patch coming out, probably soon, and in that patch, among other things, there will be a new 5-man instance called Trial of the Champion.
This instance will drop a ton of purples on both normal and heroic modes. From my understanding (and again, not even having transferred a single toon over to the PTR this time), there are 3 events that drop one purple each. The first event starts out with jousting, so you may want to brush up on your skills there. Normal mode drops ilvl 200 and Heroic is ilvl 213.
Also on Heroic, each encounter awards you with a Champion's Seal. BUT... (and this is the part I can't find a reference for) you only get the Seals if you are a champion already. So, if you haven't done anything at all, you'll need to do the 4 daily quest for 5 days so that you can be knighted by your race. (Up to you if you want to be knighted by the other 4 factions as well.) And while the Champion's Seals won't buy you Tier 9 gear, they may provide some upgrades, or at the very least a pet you can sell on the AH. :)
So... if you've done nothing for the Tournament, you need to start today. You'll complete you're 5th set of dailies on Tuesday and then you can go do the Trial of Champion and get your Seals. Then again, that's assumming that 3.2 is going live on Tuesday. And being that they haven't closed the PTR yet, I'm guessing you probably have at least another week. But don't procrastinate too long.
