Yeah, I never did get fully happy with H3's systems where you had more than two types. Too often I'd cycle and end up with the wrong grenade type in the heat of battle. However, I'm not against having more than two types available to anyone who wants them. If there are going to be more than two types though, I'd like the ability to select which types I'm happy to acquire. The HUD would adapt accordingly (it wouldn't show icons for unselected types).
