after reaching lvl 75. as lightning main. My advice is save ure seal scrolls till kage treasure released. I wont change to other main, because already attached with lightning too much. I already got ningendo and will get 1 rare from sage treasure, but all ninja still cant fit my fixed formation.
My formation right now : sasuke, iruka, MB, and oro sannin war (root warrior). And im top 3 in my server, when number 1 and 2 are both big spender.
