Advantage / disadvantage is on the top of the list of things I hear former 5E players complaining about.
I guess that's one of those 'divides' - if you like it you play 5E, if you don't you play PF2E or PF1E.
I don't know exactly what it is, just kind of sort of, so I don't know personally. I've just noticed it get mentioned in almost every single "why I switched to pathfinder" YouTube video I've seen. I guess this is a rule people have very strong stances on?
Advantage/Disadvantage is the mechanic that fulfills the function of modifiers in 5e. It means that if you have Advantage you roll 2D20 on rolls using that (usually combat rolls) and take the better of the two, with Disadvantage you roll 2D20 and take the worse. If you have both Advantage and Disadvantage you wash the process out, and since it isn't possible to have more than one level of either, once that happens its done.
I'll leave it as an exercise for the student why some people (including me) have issues with this.
