Sorting or filtering by difficulty is a good start, but wouldn't it be much nicer to have them arranged by achievement type? There would have to be a decision on whether to designate category by *how* you get the achievement (e.g, "The Bigger They Are..." for boss-kill unlocks), or *what* you get for that effort (e.g, "Classy!" for class unlocks

) but since now that I think about it, there are a lot which don't actually 'give' you anything, so it'd have to be sorted by the kind of activity that unlocks it.
I don't have access to the list right now, seeing as I'm writing this from my phone and it's half past midnight, but some ideas could be...
- A category for boss kills (my suggestion above or something better)
- A category for accumulative achievements (Pest Control, Fire/Ice x1000000, etc) "One By One" or "Every Little Bit Counts" or "One Step At A Time" or "You're Almost There!"
- one for doing helpful quests (Damsel, Lost Merchant, etc) "I'll Save You!"
- and one for the ones where you're quite unhelpful (killing escorts and whatnot) "Rules Are For Suckers"
- maybe a category for some of the weird or funny achievements "Huh?!" or "What Game Are YOU Playing?"
And I'm picturing this as either collapsible trees or some other layout such as tabs..
Thoughts?
Edit: typos
Edit2: There should probably still be a category just for class unlocks, even if that means those show up in two lists.
