Decrease lethality and increase damage SLIGHTLY for lethality items

That way, tanks can absorb more of the damage coming from assassins. To a tank, assassins should be no problem at all, but sadly they are...

And for those who are downvoting just because I said "increase damage", decreasing lethality is already decreasing damage, so just increase damage by a little to balance it out. Assassins should be able to 1-shot carries 1v1 if the assassin is ahead. Keep it that way. But an assassin shouldn't be able to chunk a tank to 50% hp.
