Zones have never migrated. The biggest change is like 2 or 3 creatures every other update. It is getting extremely stale. Especially for those who of us who haven’t been able to really leave the house for months.
The giga scents are nice and all but getting the same creatures for 9 hours a day for the past 70 days is just like come on.
Shift entire zones. Shift half the creatures in the zones. Move dusk creatures to night or day and so on.
Just spice it up some please.
PokemonGo changes nests every 2 weeks and they have 3x the creatures in their game. It can’t be that hard.
