Under the McMMOBonusPlus feature description it says that all McMMO abilities receive an additional 33% activation chance. Is this cumulative or multiplicative? That is to say, does it take the base chance and add on 33%, or does it multiply the base chance by 33%? Take the Acrobatics passive skill Dodge for instance, which has a 20% activation chance when maxed. Would the McMMOBonusPlus feature raise this to 53% (20% + 33%) or 26.6% (20% * 1.33)? I'd be quite interested in buying it if the bonus is cumulative, not so much if it is multiplicative.
