tldr; Basically a flatroll system provided by Funcom, which interact with the GUI and loot; where you can sign up on loot(need/greed/pass), and a safe transaction to the winner.
In regard of some Bot drama lately... without joining that discussion, FC sure could provide a system that made the bots less needed.
The system I'm about to suggest, apparently exist in many other games, so if further inspiration on how to design it is needed... check some newer games out.
The system should also work just as good in raid as in single teams.
When ever there is loot to divide, a leader should be able to "auction" such loot up for the team or raid, such that anyone could add in with "need", "greed" or "pass".
The loot-leader should also be able to set certain rules on the loot, such that "only need", or "need before greed". But as loot is sometimes rolled for alts, the won loot should be account-locked and not character locked.
There should also be able to set rules on how many "needs" that is allowed for each kill, etc.
Surely FreeForeAll should also be an option if desired
Anyways, this was some starter thoughts, please elaborate further!
