I don’t know about you, but I still like Argent Tournament and even though you now can share the Crusader title between all your characters (level 80 and above), I do it with all my levels 77+ until they are crusaders.
Especially since it is a nice and quick way to get some cheap heirlooms if you want to start a new alt. I just see which of my characters has most Crusader’s Seals and she gets off to grind for heirlooms (you can get 14 seals a day in Argent Tournament). Sometimes, if I am in a hurry, I send 2 or 3 to grind in the same time. At high level, it goes pretty quick.
One of the quests you can get is “Get Kraken”. You fly on a self-guided mount, and you have to throw eight spears on Kraken and kill six Kvaldir (generally you get them with two spears).
Now, if you calculate it correctly, if you send all your spears right after each other on Kraken, you will eventually kill him (generally after the seventh one). You can see the animation with Kraken dying. He reappears directly after though, but officially, he has been dead.
If you do that, then you will get a “Kraken Tooth” in your bag. It is a quest. You just have to deliver the tooth to Crusader Silverdawn, who gave you the quest originally. You will get 7.40 gold for that (and XPs if you are under 90).
The only thing you have to do is to hit him with seven spears in a row. Easy way to make extra gold and extra XPs when you are on this quest anyway.
