While reading another post someone had suggested that sinking ships should change the color of the flag.
How about a step further and the color would change based on the number of ships sunk and the kind of flag color they had.
Now to keep people from just going around sinking every ship they see players must specify they are doing a pvp flag when entering a game and white flags who are those that do not want to pvp will not give experience so it will not benefit to the next color and must be another pvp colored flag only to reach the next level.
The flag will also have a turn in value so say the first shift in color is just a few hundred gold and maybe a small amount of experience to some kind of new rep group similar to the current value system progressing up similar until the final color that has the same value as a stronghold item.
Sure there will still be people that attack the white flags for loot but this should lessen a lot of the attacks on those not interested in pvp while keeping that pvp element in.
Also if a white flag is doing a raid after so many minutes in the raid zone their flag automatically converts to a pvp flag. The crew that completes the raid also has the current level of their flag increase by 1-2 colors as an extra benefit.
