I would fuse Orderrealm and Chaosrealm with Outworld as both only really have one gimmick.

I would love to have an arena on top of one of those upside down pyramids though.

I would give more focus on building some arenas in Edenia to be honest. Give some contrast to the normally Hellish (Netherrealm) or Industrial or Feudal Japan (Outworld) stuff we normally see.

I want a focus on Vaeturnus, Nitara's Vampire realm. I want to see more with Nitara and the vampires.

Order/Seido and Chaos realm pretty much make my life worth living. keep them

I pretty much think the next game needs to come back into focusing on EarthRealm...but I like all these:

EarthRealm, NetherRealm, Outworld, and Edenia.

Almost in that order...

Outworld and Earthrealm should be the main focus. As for the rest of them. Seal em up.

I would like a focus of ONLY Earthrealm and Outworld.

I REEEEAAAAAALLY want the Asian themes and arenas to come back mixed with the creepy atmosphere of Outworld.

The more the merrier. They really need a "War of the Realms" storyline. They should have used it in Armageddon instead of the "Everybody fight to get to the shiny guy at the top of the pyramid" story. That wasn't really creative at all. But oh well.
