You can always keep the Ice Walls in hand until your Shield is down. They aren't useless?
And even if you have all your HP, you can use Ice Wall, unlike Greater Heal which is useless if you're at full health/close to full health.
Also, using "Perfect Scenarios", like drawing 2 Greater Heals per turn isn't a good representation on how powerful it is. All perfect scenarios are powerful, and deadly.
Oh, and if you take into account regular Shield cards for characters, Ice characters can easily put up 15-20 Shield every hand. (Barbarian for example)
Champions regular heals are almost always discarded because the cost-to-heal is inefficient compared to shields.
Face a Shatter-staking barbarian who only uses shatter, freeze and shields, and you'll see how long that battle takes.
Again, Shield = Health because there is a lack of unblockables in-game. Only Light characters, and Earth have decently good unblockables, even then, Blessed Strike is limited to 1.
Founder Champion is also not immortal. Healing 10 damage is not close to being immortal. Immortal = Chain stunning Ice characters pre-nerf.
