One of the problems I see with Season 2: It seems to be made with binge watching in mind.
It has continuity between every episode in a very linear succession, each a direct sequel to the previous episode. I say this is a problem, because this season as of "Life of Pie" seemingly still continues the ongoing plot that lasted since "Cute Impact", and this plot seems to have multiple subplots that are introduced each as separate sections of the plot (few episodes per section, each with its own gimmick) instead of coexisting. And it seems to feature no breaks (even the filler episodes are directly affected by the plot).
I may be jumping to conclusions since only up to half of Season 2 is available, but I theorize that they flat out removed potions from Pony Life for Season 2 and that the name "Potion Ocean" is an artifact of the concept.
