Being able to specify defence tactic in raids

When I raid and see an opponent hero about to fire off their special… if it is a directional shot (ie not area spell) I also wonder who will get hit… I assume it is set to random.

Might be interesting to be able to set up who a defense team targets…
So when you choose you defense team it should have an option to specify either:
1: Weakest hero
2: Strongest hero
3: Healer
4: Fully charged hero
5: Random
for example… and Random set to default

That way I can make my defense team use the tactics I prefer…

Thoughts?
