SCH needs help

[Volkaj]

Correct me if I’m wrong but.. wasn’t it a 300 total potency loss for every Misery? Glare is 300 potency and 4 GCDs worth is 1200 potency. You need to spend 4 GCDs to use Misery which amounts to 900 potency so that means you lose 300 potency overall. Unless I’m missing something?

You're correct in your assessment. You have to get Misery out to get the best efficiency possible, and it is a loss of 300 over spamming Glare.
That said, you used 3 Lilies worth of healing, which will usually cover a lot more than the Aetherflow equivalent.

If, over the course of the entire fight, there is less than 3 Lilies worth of healing to be done, then yes, by all means have your SCH cohealer do it.

P.S. Note that this doesn't consider the use of Lilies for movement, which reinforces my point anyway.
