Leeway exists with the exact same formula it has for the last 15 years. Hitboxes across all races were normalized though.
Here’s the leeway formula, which you can also test to confirm is the same between both games:
Melee attack: MAX(5, SourceCombatReach + TargetCombatReach + 4/3) + IfSourceAndTargetAreRunning(8/3)
Ranged attack: SourceCombatReach + TargetCombatReach + AttackRange + IfSourceAndTargetAreRunning(2)
AoE: TargetCombatReach + AttackRadius + IfSourceIsRunning(2)
I don’t mean to crush your dreams or whatever, but if they’ve never touched leeway in 15 years, there’s a reason for that. I think it’s incredibly unlikely that they’ll reduce or remove it.
