The achievement code ‘knows’ which ones we have done, how hard would it be to send out an in game mail to our character to let them know which ones we haven’t completed?
Ideally, for any ‘counter’ type achievements (when it’s applicable), it would be nice to have a 10/13, 3/4 and an expandable list that shows us which 10 of the 13, which 3 of the 4 we have in place. I know it would be useful for the dungeon runner achievements too, even the daily kill varieties.
