Honestly, there's no reason anymore for either of them to exist by themselves at this point. Low level is even easier and forgiving, since they buffed base defenses of tanks in early game. And at later points, you get so many more tools, they're both just redundant by then. For small heals, they can both just use Regen and Aspected Benefic, if they really feel like the natural HP regen isn't enough.
