Achievements for your achievement points! :3...

Slightly more serious but on the same vein, I would be cautious with anything revolving around achievement points being spent because earning them is a limited resource that is only occasionally added to. Would probably create many situations where people get really upset. I just mean spending vs reaching to, like don't make them consumable.

How could you just add fantasia!?! I spent them all on golden sparkle tier five dye already!

Why aren't you adding more achievements? I need more fantasia! Add more!

I think if they wanted to do something with them, in honesty, achievement rewards for achievement points is probably the best way to get the least amount of hate. But SE would be expected to make rewards at an interval then, also do Legacy achievements count?
