I think the only way to remove “luck” is to prevent either side from ever Mana Surging, getting a chained skydrop ever, or having spawned gems create a 4-match. The feature that’s in place is intended to prevent the AI’s luck from ever exceeding the player’s by a huge amount.
As an example, let’s say you are rolling 6-sided dice against the AI. Whoever gets a “6” gets one point, and you’re competing for score. Without a limiter, the AI could get extremely lucky (at a low chance) and could get a streak of 10 “6s” before you get even one. The limiter prevents the AI from getting, say, 4 6’s when you haven’t gotten any. Effectively, the game is cheating in your favor, though it doesn’t prevent the AI from getting lucky – it simply prevents it from getting wildly more lucky than the player.
Salty’s post was that they discovered a bug wherein that limiter was overly severely cheating in the player’s favor – say, by never letting the AI get two “6s,” in my above oversimplification – and they fixed it to properly make things more even – but not exactly even, and the game still cheats in the player’s favor, just less so.
Im not sure if this make sense or just makes things even less clear
