Neverwinter's next class, the Oathbound Paladin, is certainly meant to play off of that image. It's a class that can specialize in tanking or healing based on the Paragon path it chooses, and it mechanically centers around helping allies without thought for itself.
The central mechanic of the Oathbound Paladin is Divine Call, an ability that gathers energy passively and through certain Paladin actions. When used, it can taunt foes or offer big area healing. The more regular abilities for the class allow it to aura-buff the party, place damage shields on fellow party members, and absorb damage only to unleash it upon enemies shortly thereafter.
