I can't tell if plastiqe is being sarcastic or not...but just in case...this is a JOKE thread...=/
He's being sarcastic.
Very good job plastique, I
almost fell for it. I had already started my reply when I saw a very familiar style of writing.

Haha, that was pretty funny.
Anywho, not meaning to topic-jakc or whatever but what fi heal healed hp based on the amount of life quanta you had; like firebolt and drain, eh? eh? what'ch a think? 
You're not topic hijacking because what you say there is actually what this thread is
really about.
Not a bad idea. Something like that might work although you could then build an insane light/life healing deck with Rustlers, Shard, Miracle and Heal.
Funny thing about Heal is that even if you doubled its effectiveness (make it heal 20), it would
still be worse than Shard of Divinity. If that is not enough proof for it being underpowered, I don't know what is.
