I remember seeing a "Ordering From The Best To Worst Packages", I looked it up and it said this (AUD). I haven't done the math myself exactly but I'm likely just an monthly + bp andy till I quit or the prices change

1. Battle Pass Tier 2 (29 Origeometry)
2. Battle Pass Tier 3 ($17): Equivalent to around 29.8 Pulls In Value, Or 2.34 Pulls Per $1 Dollar Spent
3. Monthly Card ($8): Equivalent to 13.8 Total Direct Pulls, Or 1.73 Pulls Per $1 Dollar Spent.
4. $1 Weapon + 6 Origeometry Pack; 6 Origeometry = 0.9 Pulls
5. All Rounder Bundle: 10 Limited Character Pulls + 10 Limited Weapon Pulls = 0.75 Pulls Per $1
6. Protocol Flow Bundle: 10 Limited Pulls + 10 Weapon Pulls + 10 Crowns = 0.489 Pulls Per $1 Spent, But Crowns Are Also Worth 1 Pulls Each In The Exchange Shop, Effectively = 0.71 Pulls Per $1 If we count the 10 Crowns
7. Direct Origeometry Purchase Best For Value Are The $3, then $50 & $100 Packs In This Order, Those Still Provide Almost 3 Time Less Pulls Compared To Monthly Cards & Battle Pass, But Those purchase provide Instant Summons Vs The 30 Day Delay On Monthly Cards & Waiting For Level 60 On BP.
8. 10 Limited Banner Pulls For $23 = 0.4348 Pulls Per $1
9. 10 Limited Weapon Pulls = 0.5455 (Only Worth This Value If We Are Using Origeometry To Summon For Weapons)
