I feel like Pyros will have:

-NM fates for leveling
-"Bunny" fates that drop lootboxes that drop Logos actions parts
-Multiple Logos parts needed for crafting actions
-No mount at the start of Pyros
-Another lack luster storyline that can be summed up as "Thanks for getting me this now go away till you are a higher level"
-Heavy RNG and luck tied progression
-Repetitive excessive grinds
-Rare drops that you might never see drop

Though I'm just guessing here so I'm pretty sure this won't happen coming after Pagos and given how Yoshi and team loves to listen to the player community.
