@LordPerucho:
But lets be a bit serious, Vegeta didnt expect Black to pull out a Ki sword, and Goku was on the defensive, attempting to use sneak attacks since looks like he cant fight him head because of Blacks Ki sword..
Even if he didn't, back in DBZ Vegeta was a pretty rough guy to beat.
Some examples:
-in the first fight vs Goku, Gohan & Krillin (& Yajirobe I suppose) he pretty much survives everything. He actually seems indestructible.
-on Namek he gets his ass kicked several times, but kees surviving and coming back to turn the tables.
-against Majin Buu he just doesn't want to go down and keeps getting up.
To be honest, even if Vegeta didn't expect it: going down like that is kind of lame. Same happened against Beerus and Hit.
Then again I don't really like this 'sideline watching'. It was used in the fight against Cell, but didn't feel the same because of the Cell Jr.'s. And against Kid Buu it was more Vegeta and Goku giving each other some time to recharge. In DBS everyone is just standing by and watching every single time.
