As simple as it sounds.
Give the ability to the leader of the organization to set the ranks within the gang to a max of 10(?), so there's more fluidity to arrange the members and a clearer hierarchy instead of integrated ranks that we have now.
For example in most of the gangs / squads if not all of them, the VL has the same rank as HQs and the HQs have the same rank as other level 4s, and if anything the leader would have to do any changes since these positions share the same rank within the game.
Other examples can follow through but you get the bigger picture.
A format that can follow for example is:
Edit: I kinda messed up the poll and cant edit it but ehhhhhh
2nd Edit: To make it extra clear:
For the people who don't want to change it they can leave it as it is now, the suggestion is for the leader to be able to change the level cap in the gang the same way he can change promotion abilities / motd changes etc.
So gangs can have the level 5 cap as we do now if the leader wants so and for others who want it higher to increase it.
