"REQUEST] Grenade button change
https://forums.dust514.com/default.aspx?g=posts&t=67990&find=unreadUpdate: Good idea, however, it isn't clear where the grenade throw button will be after this change. "
I will try to be more clear.
Tap L2 to cycle between equipment and grenades, once you select the grenade you want, press R1 to throw it. This is just like selecting and deploying a nanohive or drop uplink. ***
It does not make sense to dedicate an entire controller button to grenades since players may not even have grenades on their fitting, making the button potentially wasted when there are much better uses for it. It would be better if the grenade button was changed to become a dedicated equipment button, and grenades button.
Make weapons and equipment on separate buttons. Tapping R2 should switch weapons, and tapping L2 for cycling between both grenades and equipment.
The benefits would be great for logistics players, because they could then be able to tap the L2 button to cycle through their equipment instead of having to open the wheel (which can be a pain in a many situations).
It would also open the door for new dropsuits in the future with multiple grenade slots, because being able to cycle through them would allow you to choose which one you want.
Most dropsuits only have one equipment slot (and heavies habe none), so switching to grenades would still be pretty fast.
One other change would have to be made though; you would have to tap (or hold to cook) R1 after selecting a grenade to actually use it.
One button (R2) to cycle weapons, another (L2) to cycle grenades and equipment; MAG had it like that, and it works pretty well for managing lots of items. You can still keep the wheels (hold R2 for weapon wheel, hold L2 for item wheel), though this would make switching to exactly what you want so fast that wheels would be obsolete.
Yes I know controller remapping is coming, but I doubt it will provide such a level of control that we will be able to separate equipment from the item wheel, merge grenade and equipment buttons, and have tap-cycle functionality.
EDIT: Add this as an alternate control scheme if possible
