2 Questions: Artillery spell timing & Morale

[Ironhawk]

Question 1: If I cast Flames from the Sky the same turn my opponent casts Gift of Health, will his troops have the bonus health when my Flames hits? Or does it take effect later on in the turn, giving me the opportunity to strike?

Question 2: Morale for a squad is the average of all of thier individual morale scores. If I mix mindless (morale 50) units in with regular (morale ~10) units, does that bring up the average morale of the squad significantly? or are the mindless units ignored or something?
