1 point of Moonlight Chain is good for combo assist if you aren't good at wall combo or just feel like taking it easy.
Moon Pieces imo should be included in full support builds. It sounds good to be a full support with little or no offensive skills but in reality not all situations call for heals, and in those situations the 'true' full support healer becomes a 'true' almost fully useless healer.
Moon Pieces are useful when:
1. Everyone else is dead and you're alone against the boss.
2. When there's little or no danger of getting killed and everyone is just trying to do as much DPS as possible.
3. Geting monsters to flinch at long range.
4. Getting rid of that last irritating mob.
