There's less strategy when Iruka, Neji and Guy all want to interrupt the same person in the same turn. Or even worse, when every ability gets used on Gaara, meaning 0 combo....
The key in Ranked Battles is positioning and having three line ups... normally the bottom lineup will be for your tanks ninja, the middle lienup your assassin ninjas and the top lineup your control ninjas.. but its up to you since everyone has their own strategy....
