Freeze vs healing spells

I have a few th10's in my clan who attack th9&8 in our wars with 3 rage and 2 freeze spells, I have told them repeatedly after watching their painful 2 stars that if they brought 2 heals it would've been a 3 star. it makes no sense to me why you would freeze a defensive turret(s) for 5 seconds when a heal spell would not only last longer but overall be a net positive on troop health.
Someone please tell me why a freeze spell would be better...I am losing my patience

Heal doesn't provide definite viability. example: your troops are getting rained upon by 2 close ADs. Heal won't be enough for that.


But in cases where the troops aren't getting absolutely pounded, heal would be better.

True about the AD, But he's freezing AT, xbow, cannons....I think it's a no brainer but how do I explain it better because obviously they way I am isnt working
