A bunch I disgruntled players came up with a math basses point system for the AoS scrolls. it seems to be broken down to the level of what weapon option a unit is even using. and them numbers are not an entirely different number scale from the 8th edition numbers. it's no perfect, but it's a web based and they plan on improving it as they test it.

That is what I was trying to do in the other thread. Theirs is a more complicated looking formula. They maybe better maths majors than I am. Lizardmen according to their reckoning NAME COSTS Lord Kroak 237 Slann Mage-Priest 137 Kroq-Gar on Carnosaur 276 Saurus Oldblood - Suntooth Maul 126 Saurus Oldblood - Warblade 130 Saurus Oldblood - War-spear 133 Saurus Oldblood - Greatblade 126 Saurus Oldblood on Cold One 139 Chakax, The Eternity Warden 119 Gor-Rok 142 Scar-Veteran with Battle Standard 102 Scar-Veteran on Carnosaur - Warblade 280 Scar-Veteran on Carnosaur - War-spear 284 Scar-Veteran on Carnosaur - Greatblade 273 Saurus Warriors - Club 18 Saurus Warriors - Spear 18 Saurus Warriors Alpha Talon - Club 19 Saurus Warriors Alpha Talon - Spear 18 Temple Guard 26 Temple Guard Alpha Guardian 30 Saurus Cavalry - Blade 35 Saurus Cavalry - Lance 35 Saurus Cavalry Alpha Knight - Blade 39 Saurus Cavalry Alpha Knight - Lance 38 Tehenhauin, Prophet of Sotek 100 Tetto'eko 82 Oxyotl 88 Skink Priest - Priestly Trappings 67 Skink Priest - Cloak of Feathers 98 Skink Chief - Golden Sickle 70 Skink Chief - Ornate Club 67 Skink Chief - Golden Sickle & Blowpipe 75 Skink Chief - Ornate Club & Blowpipe 73 Skinks - Meteoric Javelins & Star-bucklers 18 Skinks - Boltspitters & Star-bucklers 18 Skinks - Boltspitters & Moonstone Clubs 18 Skinks - Moonstone Clubs & Star-bucklers 15 Skinks Alpha - Meteoric Javelins & Star-bucklers 18 Skinks Alpha - Boltspitters & Star-bucklers 18 Skinks Alpha - Boltspitters & Moonstone Clubs 18 Skinks Alpha - Moonstone Clubs & Star-bucklers 15 Chameleon Skinks 24 Terradon Riders - Starstrike Javelins 53 Terradon Riders - Sunleech Bolas 48 Terradon Riders Alpha - Starstrike Javelins 54 Terradon Riders Alpha - Sunleech Bolas 49 Terradon Riders Master of the Skies 54 Ripperdactyl Riders 53 Ripperdactyl Riders Alpha 55 Skink Handlers 14 Salamanders 51 Razordons 77 Kroxigor - Drakebite Maul 69 Kroxigor - Moon Hammer 62 Stegadon - Skystreak Bow 245 Stegadon - Sunfire Thrower 255 Stegadon with Alpha Skink - Skystreak Bow 265 Stegadon with Alpha Skink - Sunfire Thrower 276 Engine of the Gods 277 Bastiladon - Ark of Sotek 278 Bastiladon - Solar Engine 240 Troglodon 226 Jungle Swarms 46
But the formula can't cover sinergies or special rules. There's no point in Slann who is able to summon whatever he wants, to cost less than any unit he could bring on the battlefield.
Does a formula really need to? Synergies start to happen because of player decisions. Ultimately, the goal of a point value system is to have the game decided by dice-rolls and the decisions the players make.
Presumably one would use the formula to establish a baseline. Then you would adjust the points value up for exotic non-quantifiable abilities via arbitrary decisions educated guesses on what's appropriate. Then when you find out something is imbalanced, change it again.
I would leave the points alone, and put my faith in the restriction teams around the world to cancel out broken combos
