*Yes.

*Sure. Then they cast as a Blood 5 and only take 67 +armor Fatigue. They might even cast it again, but that doesn't change the fact that similar spells do much more overall damage over battles while still being cheaper in fatigue and not costing gems.

*Reinvigoration will do just that, at the price of a blood slave and a scripting slot. Strategically, losing a slot is incredibly bad.

I'm sure your Banelords are many. I just think its hilarious to watch 60 gems worth of commander and equipment go up in smoke.

That being said, if you look at the raw gem cost and fatigue, a spell with those costs should affect the whole battlefield or whole armies. The fact that it only hits one person on the field for a decent amount of damage is its only saving grace.
