Basically just what the title says, where the maps will be grouped into two map pools with 4 maps each. Since learning 8 maps for new players is pretty daunting. And probably too tiring for even casual players.

With this it can prevent any situations where players are just one tricking a map. Which still encourages players to learn multiple maps. And it can prevent a de_mirage situation in VALORANT rather than an accept or decline mechanic for maps. Players will now choose between two map pools before queueing.

Example Map pools:

Map pool ALPHA

• Bind
• Breeze
• Ascent
• Fracture

Map pool OMEGA

• Haven
• Icebox
• Split
• (8th new map)

Also the map pools aren't permanent meaning that Riot can mix n match the map pools every act or every patch if need be. Especially if there is a huge imbalance in the two map pool usage.
