"And just like that, every warrior of light meet death, because they can't be healed any more"

Come on, you can't be serious...

Did you really think that removing healer is a solution on a game based on the "Trinity" ?

What do you want ? Allowing a samourai to heal wound by cutting with his sword in the butt of his comrades ? Or allow Warrior to just make you a hug that will most likely destroy your bones instead of putting everything to place ?

If the current states of healer was REALLY unplayable you won't see anyone killing any Savage, let alone Ultimate... Healer does have issue, that is nothing new, but it's not like throwing it away will solve anything.

Imagine you just made in injury to your foot, and you need help to walk. Do you need to fix/heal your foot, or throw you away in a bin ?
