As this is still a point of contention for some people, and based on responses I've seen in other threads about this topic, I thought I would compile some of the additional limitations/safeguards that a smart Vote to Kick feature should have. After all, we're all aware of ways a Vote to Kick could potentially be abused -- but rather than just reject the whole notion out of hand, wouldn't it be better to respond to specific abuses and eliminate/minimize them?
It goes without saying, but these are far from perfect, so let's change/tweak them as needed:
1) New players (characters who have not successfully completed the dungeon before) cannot be kicked. I suppose this would still allow new players to troll a group without being kicked out, but realistically I find it hard to imagine that a significant amount of new players would rather do this than progress. At worst, those X% of new players can only be "new" once, and it's far better than the 100% of players who have the options to troll and go AFK now.
2) No kicks may take place during combat, no kicks directly after a boss is downed & loot is being rolled on, and no kicks after final boss has been defeated. No kicking a player in the first few minutes of them entering a dungeon, for any reason. I'm tempted to include something about kicking just before the final boss, though I'm not sure about the particulars.
3) In a Light Party, you need 3 out of 4 players to pass a vote to Kick. In a full party, you need either 6 or 7 out of 8 (I'm not sure of exact number in this case, perhaps the requirement could fluctuate based on circumstances).
4) There should probably be limits on the amount of kicks a player can vote in per day, or perhaps a cooldown on kicking for any particular group.
5) Replacements for kicked players must be drawn from the random Duty Finder pool. Maybe you can manually invite a friend or FC member if the party was fully put together before originally entering the dungeon (I can imagine ways that might be abused, but they seem rare/impractical enough not to be a widespread problem. Am I wrong?)
6) A player who is kicked while "disconnected" will count as having abandoned the group, and will suffer the penalty for leaving. Apologies to those of us who get legitimately disconnected against their will, but this is necessary to deter the players who intentionally "disconnect" rather than leave.
7) The penalty for leaving is increased in general, and further increased with each group you abandon per day. Penalty for leaving a group that includes a first-timer is also increased.
8) Boss rooms cannot be entered unless all players are alive and within a reasonably small radius from the entrance to the room.
Any further suggestions? Please be as specific as possible. :-)
