Some of you guys forget Swiftcast exists, and guess what? It's a 60s cooldown. That is why I mention turning off lightspeed instead of wasting the recast and dps loss. Swiftcast a Gravity. Be bold. You have options that don't involve wasting resources.

Synastry isn't designed as an oh-snap cooldown, it should be used proactively as mechanics dictate. Just like Divine Seal, only better. (do you have to heal two targets somewhere, like A12S or Nidhogg Ex with the adds). Sitting on a cooldown over the period where it could have been used more than once is in a sense wasting the skill. Just like tanks that "save" defensive cooldowns and end up with too little migration forcing more work on healers. Rather then optimize their rotation if they use one of their best cooldowns early-on they will get 2 uses instead of 1. Or like a a lot of pugs, none.
