Lightening should deal more damage

Like the title just said, I think lightening should deal way more damage, so people will actually USE channeling (different levels) enchantment and lightening rod. Also the new copper golem seem to be a mobile lightening rod, so increase the damage of lightening would give it another use, too. Not all lightening should deal the same amount of damage, and channeling is controlled by levels so you can get brown mooshroom and charge creeper with out killing them.
