Guns and explosives should be an option together. they go hand and hand I think. Always prefer assault rifles and mines and grenades. Mines were huge in Fallout 3. Didn't need them as much in New Vegas. But I have a feeling Fallout 4 will have a lot of deadly creatures/beasts that back tracking while dropping mines and setting traps, will be huge. Was very effective for me in Fallout 3.
