First Blood...

I haven't had any issues with first blood till recently, but now it seems that all it takes for an enemy to win is a light tap, which shouldn't normally draw blood (cough cough, patting my fully armored side with a halberd), while I need to hit a full spinjitsu combo on them. Toughness is set in the middle for both me and them, so I'm bamboozled as to why the average Willie is so tanky compared to mine.
