If only purify removes all negative effects instead, but then again, what
are considered negative effects in a game like Haerthstone? Poison? Could
be used to help clear powerful minions, deal 2 dmg to all characters at the
end of the turn? Perhaps, but in the end, they didn't have enough reason
for this to be added. But for now, Priests all across the world can only
hope that Purify will have it's cost nerfed to 1 mana for better value.
