Nice to return

not like achievements in this game are very interesting.
in other games you have stuff like do this to make that boss more difficult . not to get better loot just for fun and the achievement.
do this or that content in a certain time or without dieing.
kill that entirely worthless monster you dont need for anything.
jump down a cliff of a certain height.

compared to do this content 1 time... 5 times... 10 times. do that 50 times... 200 times.... 1000 times... not enough? then do it 20'000 times.

Good ideas:
{Role} Party! : complete the duty only using {role}.
T(h)ankless {duty flavor text}: complete {duty} without having the tank role in your party.
Heals? Who needs heals in {duty}: same as above but healers.
Damage is for chumps in {duty}: same as above, no DPS.

yes. just a tiny bit of creativity and you can end up with more interesting achievements. not for everybody but for more people than now.
adding replayability and variety without having to make a lot of additional assets. and also pushing some people to do stuff differently without forcing them. (not just the game is stale. quite a few players are as well)
