Party leaders can be quite the dictators and this is not always a bad thing but this power can be abused. I have never personally had problems myself but I have witnessed them as well as read about them on these forums. There needs to be a limit on the situations which a party leader can kick other players.
-Kicking players from a group should be democratic aka voting. (Anyone can initiate a kick and everyone else votes.)
-Players shouldn't be able to initiate a kick while dead. (Party leaders have been known to blackmail players into rezzing them.)
-When a kick is passed the game should act as if the kicked player used the "Go Solo" option. (Sometimes players invest a lot of time into a run and shouldn't have to yield that investment.)
I admit that I do not fully understand what happens when kicked from a party whether a player is returned to haven or if my suggestion is already a part of the game. Regardless it seems important this is implemented because there is no reason to return players to haven when the functionality of splitting instances already exists.
kick = forced solo, but you lose your heat, vitapod, and vials.
