Yeah, there is an achievement for getting all 10 Tomo Answers wrong. I saw the one about having all three dragons KOed in the coli, though I missed the one about Higher/lower (that one would be super easy for me :P)

So, yeah, not all achievements are 'positive'.

Exalting is part of the game. Dragon restoration is part of the game. Achievements are little 'awards' for playing the game, which includes exalting and restoring dragons.
