What happened with Ritual, Delirium, Essences?

I really can't understand why in poe1 we have good working ritual and delirium, but in poe2 we have bad ritual spawn, not working ritual altar, delirium mobs push you after spawn, delirium fog don't move on map and stuck.

Looks like poe1 league did another team.

Essence with 5 mods weaker than white mob.
Greater essence is a really lucky, but it breaks craft.

Maybe will we think about balance and bug in current leagues mechanics?
