This is where I find P2W very subjective. My definition has been people being able to use real world money to gain an advantage over others. Skipping the story doesn't mean you'll be able to clear any content without learning how to play your job, thus I don't feel a jump potion is P2W. Now if SE added say, Beast Tribe token bundles to the MogStation so people could skip the Anima grind. That's when you start crossing murky waters imo.
