I'm most likely not the first to suggest changing the B/P level names, but I've had the idea brewing in my head for a while. It feels awkward for the point ranges to vary within "tiers," so I figured changing the level names and icons so they're matched up with the different point ranges each level has would make progression feel more natural.
Civilian Tier (100 points range)
L0: Civilian
L1: Town Watch
L2: Scout
L3: Safety Patrol
L4: Security Recruit
Portal Security Tier (500 points range)
L5: Portal Sec. I
L6: Portal Sec. II
L7: Portal Sec. III
L8: Portal Sec. IV
L9: Portal Sec. V
Enlisted Tier (1000 Points range)
L10: Recruit
L11: Private
L12: Corporal
L13: Sergeant
L14: Warrant Officer
Officer Tier (1500 Points Range)
L15: Cadet
L16: Lieutenant
L17: Captain
L18: Major
L19: Colonel
General Tier (2000 Points Range)
L20: Brigadier
L21: Major General
L22: Lieutenant General
L23: General
L24: Field Marshal
And last but not least, the Ranks of Tanks.
L25: B/P Master
L26: B/P Grandmaster
Like I said, this is just a cosmetic change, but I still believe it would improve the experience. Alternatively, we could take the standardization further and name the levels Scout I-V, Security I-V, Soldier I-V, Officer I-V, General I-V, and B/P Master and B/P Grandmaster, but I don't know if this would remove the charm the B/P Ranks have.
