What is the point of Realms ?

[Tigerious]

Hi,

Since the Raven + Horus merge and the official statement of allow multirealming, I would like to know what is the point of having 3 realm?

Most of the players just left the weak realm and join one of the two others when they "think'" they are underpopulated etc... When they don't do this, and are in their "secondary" realm, they just come and disturb invasions plans while we don't even see them coming to fight rest of the day.

Atm Ignis realm is like a no man's land since they are devastated, not so hard to guess what happened to them.

Is this intended behavior of gameplay?
