TBH I have a couple of ideas for this. A.) The first button on the medkit has no cooldown and drops low hp healing medkits that heal. This could be specced into to provide healing to a short radius around you. Thus allowing the second and third button to be used to provide other buffs like retaliation and fury. B.) Allow the first button to drop 2-3 medkits with the same healing it has now and the second and third follow the same as scenario A. Any thoughts on this idea?
