How to frame a comprehensive army/detachment ranking system.

[Tawnis]

So, I've been playing around with the idea of doing a bunch of faction/detachment deep dives into how well various armies play on the tabletop. It's not going to be an meta analysis, but more of a conceptual one. Say for instance with the Sororities Penitent Host detachment, the ratings would be based exclusively off the units designed to synergize with that detachment regardless of what supporting units would be advantageous, whereas a detachment like Hallowed Martyrs would look at the faction as a whole.  I think I've narrowed it down to 5 categories that cover most everything, but if there's a key piece I'm missing or an X factor that needs addressing, please let me know. Also, I'd love to you if you think this kind of advanced number crunching would even be interesting in general. 

Maneuverability: This would take into account the average range of units movement, as well as abilities like fly, auto advance, scout, infiltrate, Deep Strike, Advance/Fallback and shoot/charge, as well as transport synergies. 

Durability: This would focus on the average T and Sv of units as well as Invuls, FNP, Stealth, Damage reduction and resistance to MW. 

 

Objective Control: This would factor in OC score, LD, as well as abilities like sticky objectives and battle shock. 

Ranged Capacity: This would be accuracy, buffs as well as approximate output against various types of targets GEQ, MEQ, TEQ, Light vehicles (T10 or below) and heavy vehicles (T 10+). 

 

Melee Capability: More-less the same as above, just for melee rather than ranged. 

 

The points lens: This one is a bit more mutable as points change on the regular, but to have some factor to apply a ratio of points to unit effectiveness as what it's doing for the army. 
 

I'm curious if the data I come up with will be anywhere close to where factions and detachments sit in the overall meta and/or if they will align with the general feel of how strong an army is to the general player base.
