Lets see.

5. Ground units=> Max healing effect 133 per second, Max damage of single point defense 99 per second
6. Clan castle troops=> CC of wizards will kill group of giants under heal within 2 seconds.
7. High level walls=> Lvl11 walls have 7000 hitpoints, by the time the giant break through heal spell is over.
8. Base design=> Good base design can keep giants/hogs running in circles.
How is healing an immortality spell or even overpowered?
