I'd honestly prefer if all the healers had an energy drain equivalent, but since that's very unlikely to happen, the next best option would be for SCH to not be uniquely penalized for using a major chunk of its toolkit. It works great in dungeons, but it's just not worth the trouble it causes when paired with a cohealer.
It distorts the entire healing meta for the same reasons AST's unique 1.5 cast times forced it to do everything in ShB, the situation is just reversed here, with every other healer having to go out of their way to accommodate SCH.
