It would be nice to have built in mechanisms to stop people from breaking the following rules: Kill-stealing - The act of attacking bosses or monsters on a map persistently without the system designation of ownership via the ~mapowner in-game command, or alternatively last-hitting any bosses or monsters on a map without that same designation, without the expressed permission of the player who does have that designation. Map Looting - The act of looting one or more items dropped from a boss monster, regular monster, or other map element without the system designation of ownership via the ~mapowner in-game command, or alternatively without the expressed permission of the player who does have that designation. These rules were put into place to improve the experience of players who wanted to grind without have to "fight" for their right to do so in a particular map, and are enforced by bans when evidence is provided. Nowadays, these rules are getting less-informed newer players punished for a rule they didn't know existed. I think a better way to enforce this rule is to give mapowners the ability to designate who can kill/loot in their maps (not including event maps, pqs, and boss maps). I envision a tab (like the party tab) where you can add people manually and select some check boxes such as party, guild, alliance, and buddies can loot. With a system like this in place, the rules above will no longer be needed.
But with a hard baked system like this, they'd need to also set it to only affect the LAST map the player (individual person, not character) took ownership on. Otherwise, Players will be able to easily choke other players out of multiple channels, which should not be how a system like this should be used.
For this particular issue I think simply making the timer before someone else can loot longer, maybe extend it by 200%. It doesn't really matter when it comes to bosses since we now know if anyone loots something.
