Guardian Arkveld sets an example of how Trial reward structure should be

[Miradelle]

I would like not to farm 99 tomes or any other currency for a mount - It's dead boring and it doesn't prove anything of a value.

Theeeeeen ... don't do it!

It's kind of like not wanting to do all the relic grind for the relic. At least with the extremes you can wait a few years and you can oneshot them.
