The higher tier factions should face this issue, not only us.
We're initiating a request to GREE to make it possible to boot players during WD.
Some players will promise heaven and earth to join a faction and can perform during FvF and even donate in game cash generously but when it comes to WD the promise of gold / pledge of points can go out the window and the faction is unable to do anything about this.
The game is tough enough at a competitive level with gold being being bought and put into use. To literally carry dead weight is to introduce an ersatz human dynamic into the game which makes strategies untenable given that we can't physically strangle players who promise 'A' and deliver 'a' since faction rankings in WD are a sum of the parts.
Please do consider allowing this option to exist GREE. Thank you for your consideration.
