Wait..

Are you really saying Kakuzu is hard to play ? wtf

Actually only counters are chakra draining for EARLY rounds and weakness debuff. So there is not much counters since Kakuzu have 3 supports ninja which can give the chakra drain back (kakuzu + asuma team s*ck IMO, only good for speed kill)

The 250%defense scaling is just absurdly OP. We need more weakness ninjas before kakuzu will fell down.
