To be honest, they're adding too much parts of lore that the actual lore of the game detailed by previous chapter is confused instead:
Too much questions, few answered and more added instead, so I understand why people are confused about this. I trust Jan and the team and I know they'll answer within next version. I think these are the cons of the update, but within the rest, is pretty good: characters, revamp in many parts, add more regional forms (in 13.5, it seems like the Aevium forms are the triple of before), add legendaries before the endgame (it's sometimes a risky choice, but right now, they've done well within these), artworks and list goes on.
