I'm gonna be honest here - this one wasn't that hard for me personally. I did fine with my Ukon Sakon - Sasuke - GNW Kiba - MB team, although that might've been due to the sealing slash that I never see any of the MBs use anymore (on my server at least)
So...maybe I'm just being really dense here, but...exactly why was this one so difficult for so many people? (not trying to be offensive - just curious...)
