So from what I know, holy priest use their emergency heal as normal? If I'm going oom would that mean not enough spirit or too much flash heal usage? Since I believe holy priests should be stacking heaps of spirit this shouldn't be a problem though right?
Also, is flash heal used like a normal thing for Holy priest? Like someone is at half health or something but not in danger, no serendipity stacks. Just use flash heal like a paladin using divine light? Or HW serenity and let renew top them back up?
