One example is the "Patch no. 1":
The tooltip informs you that your chance to deal the first strike is "50% higher". What does that mean? The initial chance should be 50%. Is the resulting chance 100%, 75% or something else altogether? Do player get a "roll" when the fight starts, i.e. does one player start, get a 75% chance and if they dont start, does the other get a roll with their 50+x%?
Similarly with many, many other specials, especially the "Porn sticker":
What does "Your trophy penalty is reduced by 30%" mean? If the penalty is 80%, is the new penalty 50% or 56%? In any case, it would be nice to know what exactly happens.
Therefore, taking the "Patch no. 1" as an example, for usability reasons, Id suggest building the tooltips something like this (adding fuzzyness in this case, but making it clear how the fight would roll):
