By all means do NOT get him. Don't waste your hard earned cps especially in your case a new f2p player. A year ago jonin was arguably the best offensive 1v1 ninja in the game now he's washed up and completely overshadowed by six paths naruto, kakuzu deidara etc. it's too late to get him now, he's just not good anymore, his damage has fallen off extremely hard and by that i mean his bond skill is literally the only thing in his kit thats gonna deal actual decent dmg and its every 2 rnds. His standard reset ratio is * even with the scaling plus his dmg scaling is absolutely nonexistent. Btw upon release his passive used to boost crit rate and combo but it was legit game breaking at the time so they changed it to what it is today. Anyway he's just not worth it my dude rather save up those 13k cps and buy yourself a six paths naruto. He's every budget players best competitive choice.
