I think the new scoring system will actually give some overdue credit to your members who help with healing and stealthing. We obviously don't devalue these services to the faction because we are now giving them points for it.
I love the theory behind your proposed system but what if we stacked a mask on top of the numbers and modifiers to make it somewhat understandable. Something any person joining factions could say "I get that!"
Proposal
When a person joins a faction they declare what capacity they wish to serve the Faction by declaring the Division they wish to server:
Soldiers, Scouts or Crafters
Soldiers: Earn rank from soldiering type activities like killing enemies, Defending their faction towns, faction spawns and strongholds. Raiding enemy towns, spawns and strongholds.
Scouts: Earn rank from things like tracking, stealthing, detecting, stealing, trap removing.
Crafters:Earn rank by crafting: making traps, making faction artifacts, making faction weapons, making faction armor, sewing faction clothes, etc
WHY?: Each division would use the same formula you are developing to determine rank with some factors being weighed universally (using abilities in faction locations, in the presence of enemies, etc) and other factors weighed more heavily based on the Division's purpose.
Each Division would have ranks from 1-10, Rank 1 being the bottom 10% of that Division and Rank 10 being the top 10%. This will keep a Soldiers from having to compete in rank against the person stealthing outside the base all day scouting or a crafter banging out 100's of faction weapons. It will compare people with similiar roles in the faction, apples to apples so to speak. Thus if Soldier A is higher rank then Soldier B, he is probable doing a better job fighting and protecting his base. This way people don't have to worry about complaining, "I fight all day and that guy does nothing but hide, stealth and make endless katana'a in the base, Why is he a higher rank then me!"
Also saying "show rank, showscore, or punkte" should show a player his/her rank which is a simple 1-10 rather then the score which from the examples looks more like I'm at Skara bank asking for my account balance. The raw scores however are useful to players in that they can use the boards in the faction strongholds as a guideline as to where they are strong and where they can improve.
Adding Divisions would also help you catch potential exploits, isolate problems and make necessary adjustments. If for example all the top ranks in the Soldiers Division ended up being mages and archers because range and their abiltity to deal out damage over time. Then it would be easy to see that adding weight to melee damage might be important. The data could also be used to support balancing issues in pvp. (For example, is *blank* really over powered? Well every faction on every shard has the same template dominating the top ranks, could be).
In addition to Division within the Factions, I am a strong believer in rp, story and keeping the Factions true to the founding principles. The Virtue Faction should not be led by JakeMeUP Murderous Necromancer.
Therefore the universal scoreing ranking system should be applied differently depending on which Faction you are a member. Virtue Faction based on Karma, Free Traders based on own merits and Guardian based on Fame.
Virtue Faction: [Rank advancement capped by Karma]
The Quest of Virtue is not one of conquest but one of the righteous duty. Only Virtuous Men and Women of the highest moral character can save Felucca and its people from the surrounding darkness.
Karma Level:______Title_____________Max Faction Rank:
[-1<]__________Rude or Lower_____________0 (Deserter)
[0]_____________No Title_________________1
[1]_____________ Fair__________________2-3
[2]_____________Kind__________________4-5
[3]_____________Good _________________6-7
[4]____________Honest_________________8-9
[5]___________Trustworthy______________10 (Knight of the Codex)
*A Murder (red) can never achieve a rank higher then 0 regardless of current Karma level.
Free Traders Faction: [Karma and Fame have no effect on Rank]
All men and women who fight for the Free Traders may advance as far as there skill and hard work will take them. Let them be judged by there industry not some dogmatic view of the world or hollow reputation.
Guardian Legion: [Rank is Tied to Reputation]
The Gaurdian Legion does not allow just any lowly soldier to lead, only a Warlord of great reputation, earned through the trials of combat is worthy to command the Guardian's Legion.
Fame Level:______Title_____________Max Faction Rank:
[1]_____________No Title____________________0
[2]_____________Notable___________________1-3
[3]_____________Prominent _________________4-6
[4]_____________Renowned_________________7-10
[5]_____________Lord/Lady__________________ -
*Commander of the Guardian Leader must be at least Renowned [Level 4]. If an election for Commander is a tie, the candidate with the higher Fame is declared the winner.
