I've always wondered why cards which start out at 15% proc ends up at 20% when maxed, while cards which start out at 20% ends up at 30% when maxed. By that logic, shouldn't 10% proc chance cards max out at 20%? But no, they only max out at 15%. Could someone explain to me WHY they designed it at such? Why is there a need for such disparity
