Hi! My favorite thing to do in MMOs is to try and get as many achievements as possible, specially those that people don't usually go out of their way to get.

I think it'd be super interesting if achievements showed what % of players have obtained them (kinda like Steam does). I reckon this statistic would satisfy achievement hunters like me, and would also prove interesting to look at for the rest of the playerbase (you'd be able to, say, know what % of players finished ARR, or maybe did a specific extreme trial, or soloed POTD or HoH, or own certain relic weapons, etc.)

Furthermore, (and quite ambitiously, I know) perhaps it could be extended to the title/minion/mount selection screen and a sort function could be added? that way people could show off their rarest title/minion/mount.

Let me know what you think in the replies. I'd personally love such a feature.
