Hi. I suggest adding hard achievements to the achievement dairy. Would be awesome content for people grinding, apart from just grinding XP.
The achievements aren't supposed to be easy or done quick, but be a challenge.
Numbers could be changed for specific achievements.
Would like to get some feedback on these. They all seem pretty doable for end-game players.
