The problem with the current blocking system (Taking a % of damage off) is that because hp and damage figures are so low, it's very hard to adjust without making it very overpowered or underpowered one way or the other.
I mean, I can get it reverted to the old system if you really want too - but there would have to be a general populace vote on the matter before anything changes since it only seems to be one person that wants any changes at all
