SGE looks fine TBH. The only issues are Pneuma and Toxicon no longer being DPS neutral (which doesn't make sense for a variety of reasons: WHM movement changes, the weird cost-opportunity, etc.). If they fix that, I think Sage will play pretty well. It probably still won't be meta but hey.
Of course, making healers more distinct from each other probably means that shared SCH/SGE mit sheets might become harder to put together for things like ultimates. But I think that's ok?
