A couple things on the tournament quests:
1. Once you are a Champion of all 5 cities you no longer get the Valiant quests. This is minus 52g92s a toon per day if you did all 4.
2. On the duel quests if you are mounted you can not help the toon doing the quest. If you are not mounted you can. The key is to keep the opponents shields down so your damage means something.
With practice you should be able to get to the point where you can defeat an opponent in under 1 minute most times. With 5 toons doing both Valiant (3 kills) and Champion (4 kills) versions You can get this down to ~35 minutes. In 35 minutes you will earn 13g23s x 2 x 5 =132g.30s. You get an additional 10g x 5 if you pick the champions purse. For a total of 182g30s. For 35 minutes. I think it is a heck of a deal considering there is no travel involved.

If you have 2 guys mounted and keep 3 down. Knock bad guys shields to zero you could probably kill a guy in 20-30 seconds. Rotate to mounted guy #2 while mounted guy #1 waits for the heal to come off cooldown. Repeat and rotate them through. You might not even need to heal between fights and use 4 toons to blast further reducing the time it takes.

Even if you do not want any of the rewards available you can still profit from this further. Every 8 days at champion you will earn 40 tokens if you do all 4 quests available. With 40 tokens you can buy a pet. On my server Pets are selling for 3-8k still. I fully expect this to go down over time as more people gain access and the hard core collectors get their pets. I do think that you will still be able to sell the more popular pets for 100-300g when the market bottoms out. So an additional 500g minimum, more in the near term, every 8 days. 9 days if you skip one quest. Near term this could easily be 5-10k or more every 8 days for the next few weeks if your server is like Uther at all.

If anyone thinks they need it, I can do a write up on how I beat the Champions quickly. Not that I am a super star or anything special but I helped my step mom (who boxes these dailies too ) go from winning 1 out of 3 or 4 duels - with an alt DPSing the NPC - to finishing the Valiant version in under 5 minutes for both of her toons with no help, she is even faster now. It took about 5 minutes of in game Demo time and talking over vent.

If anyone wants me to write it up, I will start a new thread.
