Halo 4 Map Layouts

I’m sensing a trend with 343i regarding map layouts.

Almost every single map has a ton of tunnels/caves/corridors that breeds nade spamming and camping.

-Adrift
-Abandoned
-Exile
-Longbow
-Meltdown
-Solace

Can we have more open maps so less nade/camp fest will occur and more usage of guns?
