I like the idea. I mean, I wouldn't be one to pursue with it, but this would actually give a goal to playing graal.
Honestly, there are very few goals that you can achieve. I don't know why people may be opposed to the idea. Finally a goal you can try to achieve without needing a team or being completely solo.

It's literally either this, or being the best afker, farmer or hat hunter. Sparring, with the exclusion of tournaments is mostly for yourself.
