What would you like to see return from MGO1/MGO2 in MGO3?

I want Sneaking Missions to return, and classic maps that have had different variants in both games.

I am also hoping those voice-changing smoke grenades will be in MGO3. It was always so fun playing as serious unique characters such as Liquid Ocelot and having a super mouse-like voice, or having a deep monster-like voice while spamming voice commands.
