@the guy who asked about the rewards. The rewards are: rare quality versions of all 4 celestial pets and a marked flawless battle-stone - each of these cost 3 celestial coins and some other pet supplies for 1 coin.
You get 3 coins on your first completion of the tournament and you can completely it every week afterwards for 1 coin.
Back to the quote. The rewards are quite worth the effort and just because the thing exists doesnt mean everyone should have it. I'm glad I could beat it on the PTR with all these pets I am given there for free but I am more than certain I wouldn't be able to beat it on live especially since there are barely any good pets that can be caught from the wilderness.

EDIT: Very happy I was able to help :P
I had a specific reasoning for creating this guide. I usually don't do things like this and avoid doing so but this time it was different. I searched the net inside out and couldn't find any helpful information. There were some tips here and there in the US's official forum thread but they werent really helpful. I needed help and there wasn't anyone to help me. Not even on wowhead which was my biggest hope. And so I decided to make this for the others that were or still are in the same situation I was in.
