go for Ay 3rd team, you'll get a whole team instead of 1 ninja [roshi] i have roshi at around level 71 without proper equipment hes really squishy even paired with sailor + water main + healing tips lightning blitz would slaughter you.. he really needs to be paired up with han for higher survivability percentage with buff removal which most likely means damage reduction, i had the same regret if only i have pulled ay 3rd team i could have done better in terms of having a full team to work with versus a single ninja. but later on while developing him max moods + injury + critical and HP stats he'll be decent and also don't be shocked if you used him in arena and dies round 1 :D
