What about layering for realms that are super populated on side. There are certain advantages to having layers. All realms should be layered if any are. Farming for AQ event? Layers op.

Implement connected realms. Split the giant realms into two realms then reconnect them. The smaller realms connect multiples to make larger well balanced. The heavy horde, connect to heavy alliance. Connected realms are the solution here, not layers.
