This is the quintessential Medic deck build in the game, with very little room for variation when it comes to committing fully to the role. This build requires a fully cooperative team, as you will not be doing the carrying. Doc can naturally heal her entire team, and Charitable Soul and Support Scavenger ensures that she will almost never have to heal herself directly.
Rely on Bandages that scale excellently into the late game and save yourself the copper. Don't buy Medkits! Teammates should buy and carry their own healing items and they can drop them for you to use on them. Remember to play like a healer and avoid engagements if at all possible. Melee players already heal themselves and the team so it is best to save your bullets for specials.
The revive bonuses are somewhat optional and the build doesn't include Avenge the Fallen or Inspiring Sacrifice, but this should be tailored to your confidence in your group and how well they can stay alive.
