I really hope we don’t just have “Male/Female voice 1,2,3” for the next 10 years. Anyone can rock a modern voice callout or turn them off. But I feel like if they release future spartan voice packs with a unique personality, it can encourage use of Spartan voices and make your spartan feel more personal. Kind of what they did in Reach when you can literally use Chief’s, Cortana’s, and Johnson’s voice lines for Noble 6 in multiplayer but this time with new voice actors.
I also want to say is that I’m sure nobody actually uses Spartan voices for their callouts. It should be used for a socially. These are spartan IV’s, some should have personality but never trash talking. Like the spartan with the country voice with the “Over yonder” (lol). It can also encourage more customization content.
