Introducing to you : CreepScoreValue (Gameplay Update concept)
The idea is basic, Creep score only goes 1 to 0, where 1 is when you get the last hit, and 0 when you don't get the last hit.
The idea is simply : Some minions will grant more or less than a value of 1.
My current thought : Wen last hitting a Minion, it'll grant a CS based on their gold value. 20 gold -----> 1 Creep score value (CSV) When you check your score, it will pretty much be shown as currently, decimal number is rounded up for visual, but accounted in the calculations.
this will also resolve problems around summoned minions/jungle minions, who goes to 2 gold (Malzhar minion) up to 100 gold (Red/Blue buff).
So here an none-exhaustive chart of potential new CSV with this system :
Siege Minion : 46 gold /2.3 CSV Melee Minion : 20 gold /1.0 CSV Caster Minion : 18 gold /0.9 CSV Big raptor : 62 gold /3.1 CSV Mini Raptor : 10 gold /0.5 CSV Red Brambleback : 100 gold /5 CSV Zyra plants : 5 gold /0.25 CSV
