I started almost 3 years ago. There were only few p2w ninjas not like today :). There were quite few strong teams then but in my opinion two of them were really strong. 1st was Naruto Sage-Gaara-Iruka and wind main. Clones had so much shield you coudnt event get to hit anything else. And the other team was Kimimaro- Kabuto-Sakura and water main. 3 star Kimimaro would just get so much def and resis you coulnt do any dmg to him. And you would just die from the poision. Later on Roshi-Han teams took over. Good old times when difference between p2w and f2p wasnt that huge like today. Less power functions so it was much harder to power up.
