Ahum, because no ‘suggestion’ forum exists as of current, I am posting this little suggestion here.
The “Admin Lower Ranks” guild access is too general and makes it a bit hard to manage a guild, I recommend splitting it into “invite”, “kick” and “promote and demote” privileges, also regarding the last (promote and demote)… Please, make it impossible to promote somebody on the same ‘level’ as you, because I’ve seen an officer promote somebody to the ‘officer’ rank (just for testing purposes), which can be quite troublesome.
The current guild system surely needs lots of rework.
