A rather easy "fix" for Chain Heal would be letting Ancestral Awakening proc from Chain Heal, too. Other solutions could be lowering cast time, making the 100% increased glyph radius baseline or increasing the healing by 100% and mana cost by 50%.
Just my 2 cents.
EDIT: And yes, its' use is very situational. Just a spot filler heal here and there, or spam for a while when you need static AoE healing in a tight group, or spam it while Ascendance (where it actually works just fine).
