I would like to see this for combat areas so we could use an ammo synthesis easily as I know during long encounters sometimes ammo doesn't drop even without juggler active and I have to use one and will dies as it takes precious time for the menu to load up then have to select the ammo synth and use it. Balance that I could see is not make it instant and you have to hold down the dpad direction for it to actually use it. Honestly not sure if I would support it for switching to heavy weapons just because of pvp balance as pulling out something large should take the delay holding down the switch weapon button already does. Just my two cents on it.
