As leader of anarchy i highly commend Alpho on his effort and ethic towards improving Basing for us. Gang points is what distinguishes west from the other servers, excellent idea however be careful not to make the items to overpriced/underpriced or event items too overpowered or it will upset people and turn them off of basing (like the highly debated event staff).
Basing is fine at the moment however i think you should make it singular and individual points, for example for every 1 minute you are in the base you get 1 individual point and 1 gang point, the players can have the option to turn 1 gang point into 0.25 singular points, or they can donate x amount of points to the gang bank.
This is just an idea in which gives players the options to earn gang point for themselves, and their gang possibly (unless they exchange it for more singular points) the reason i think the ratio of gang points to singular points should be 1/4 is because i think donations to the gang should be encouraged as this shows who's willingly able to put themselves out for their gangs advantage, besides they are still getting singular points 4x as fast as the gang points if they convert.
In the gang bank should only be gang related items which can be used in basing, i dont think cannons would be a good idea (i heard this mentioned earlier, as it is ridiculously hard to program (think of poor Alpho haha) and it would take the gun combat out of graal in which we all love and turn it into a turret game if you wish. the items should be things which help members but only on tag and available to some ranks. This opens up a whole new pathway on the area of ranking (I'll make a thread soon)for example the leader can select which members have access to what, for example member x has access to a gang pick axe whereas member z doesn't.
There also needs to be a tool in which all players of the gang can see which player has donated how many gang points, this could help the leader do rankings depending on the donations and encourage other players to thank them or follow their actions. This aspect reminded me of the clash of clans donation system (players can see how many gang points have been donated and by who)
Another thing to take into account is to give the upcoming gangs a chance, for example, if you made the items available to gangs too overpowered then only the "better" basing gangs could get it which minimises uprising small gangs.
These are just my ideas conveyed into a spam of my own opinion haha, I'll post a proper thread soon on the subject of a whole new ranking basis.
