I actually disliked Hydatos more than the current Pagos.

In Pagos at least you have an active Fate train and you can actually do something, like killing Dragons. You can also solo farm light effectively if no one's on bunnies. I completely agree the amount of Frosted crystals required is too high though and the rng on light is tedious.

Hydatos you struggle to get a Fate spawn group going, there's no real train and if you want the mount you're better off afk'ing at bunnies and just picking up Fates as they go. When people are in BA, activity drops significantly. Crystal drops are low and you really rely on Ovni and the Support Fate to get anywhere. The instance itself has nothing new from Pyros. Hydatos was extremely dull.
