[Suggestion] Boound-on-account Achievements.

[iamferreirajp]

The achievement system has great value and in order to make it more fun to players i would like to suggest is to create a new field for the achievement telling if its for the character only or for the account. The reason for this is to determinate if all the characters of the account need to do the achievement or just one of the account, to prevent exploit, farms etc.
