343i, please add an additional keybind to cycle through grenades (like in classic Halo games). This current system may be nice for some, but it is objectively slower than the old method. Also considering now we only have two sets of grenades that we can carry at a time, these extra actions to switch between the two are absolutely not needed.
Just make it a 1-button switch between the two or add a toggle to allow it. I’ve never felt more awkward trying to switch grenade types by pressing more buttons than is actually needed.
