How about a three rule system within the structure of Dungeons to make these type of occurrences less likely – and yes all three rules coded in together, rather than just using one idea over the other. I’d impose these three rules for ANet to test out, and hell if anyone wants to change something to make it more efficient or point out flaws, please do so as this will generally help everyone. Ah and these rules would be coded into the game of course – sadly not being a programmer, I have no clue as to how this is done, this would just be a general outline for the lamen – that was referring to me;
Rule 1) After a party has gotten into said Dungeon; Anyone that has been added to the party after the original party got in, cannot join the instance at all. (This means that people would have to go out of their way to cause ‘grief’ considering that no one else can join even if they add someone to the party.)
Rule 2) There is only a brief 2 Minute window of kicking someone in the party when said party enters the dungeon. Now some may question why Rule 2 exists when Rule 1 stops anyone joining the instance after a party has entered, and the reason is simple; if someone shows signs of being AFK then this brief 2 Minute window should be used. Once the 2 Minutes are up, no one can be kicked as the kick function would just be greyed out/disabled. (Again, someone would have to go out of their way to ‘grief’ which means that those who are not AFK have all the more reason to state their arguments to a higher party – no pun intended – such as ANet. This also helps regulate how one will kick. Considering that Rule 1 stops anyone new from coming in, it stops someone getting into the Dungeon and kicking to invite a Guildie/Friend right away. If someone were to be rash and kick right away, then they’d be 1 person down for the Dungeon. Also this part can be taken out of the Rule set since it still might be cause for ‘grief’.)
Rule 3) Players are still able to leave the Dungeon themselves, and only by their own say-so; meaning, short of a player actually pressing the ‘Leave’ button, they cannot be kicked. This Rule helps implement a system where if the Dungeon seems to be too tedious of a task to complete, the party has the option to quit and try again later, or just to quit and regroup with other members. Also if someone decides to AFK past the 2 Minute mark, then well, members still have the option of leaving by their own will if the AFK person in question doesn’t showcase any chance of coming back.
Short Form: Why not implement a few Rules (in this example Rule 1/2/3 would be used together, not just separately) in the coding of how Dungeons work to exclude certain functions within certain Maps. For example, when one enters a Dungeon Map (any Dungeon) then certain functions like Kick are greyed out after a set amount of time. Follow that up with other Rules in the coding and ANet could regulate how people tend to abuse kicking players for Guildies/Friends.
