Add "Ban" to Leader's options?
I love this idea of a blacklist in the game. right now our clan has a number of people keeping unsynced copies of ban lists everywhere on notes, spreadsheets, etc... banning someone from a clan is a very abusable thing, so I think it's a power that should be limited to clan leaders. The way I'd like to see this done is in the menu that pops up when a leader taps the menu icon on a player's name in the clan's roster. The same place a leader would go to promote/demote an elder, etc. The menu item would be "Ban" alongside the other buttons like "Kick Out", "Promote to Elder" etc.
This way the leader would only be able to use it on an existing member of the clan that they don't want to see anymore.
Whatever the implementation, some kind of blacklist needs to be in the game.
