I'm wondering, on thinking about it some more, if Battlefield Healer and Inspiring Words is too strong. I was going for an equivalent of 2 Cure Wounds (Level 2) and 4 Healing Words (Level 1) (assuming a party of 5) for third level, but then I made them recharge on a short rest.
Add in that they get their Leadership Style at 3rd, that seems like it makes them way too powerful.
Should I separate out Battlefield Healer as a Leadership Style, such as "Combat Medic" ??
Also, if we're looking for solo capable classes, should I add back in the Second Wind feature? And perhaps an Extra Attack (that still couldn't be used with Exploit Opening)?
