the jonin you put in play should be making up for the -1 to hand, either by gaining you something or hindering your opponent. 1 card doesn't make that much difference, especially when it means you don't lose your turn 2 ninja.
I'm not getting into the hand advantage argument though. Oldest and most annoying argument around.
