Ninja are confused and attack their own team with basic attack, the ninja still generate fury.
Damage over Time effect in depth guide here
Physical Defense - Decrases damage taken by Physical Attacks – Scales with your Force
Strategy Defense - Decrases damage taken by Strategy Attacks – Scales with your Chakra
Incrases the damage done – Scales with your Force/Chakra
The ninja with highest Speed attacks first – Scales with your Agi
These are questions I see and get everyday and my answer is usually the same. Look at the pros and cons of a ninja and take what suits you best. There is no absolute answer because each case is different, each person has different reasons, different progress, different goals and different limits.
While player A seems DoT effects as something almighty and something every ninja he buys should have, player B does not care about them especially because he has the attack to break defense in PvE.
While player A prefers damage rate because he can out speed anyone in PvP player B prefers avoid injury because he knows he will not attack first and that extra avoid injury lets him survive.
While player A prefers chaos as solution in PvE player B does not care about it because he can’t even attack
While player A prefers Toneri for the utility player B prefers Shin and Christmas Itachi for the passive speed buffs.
I could go on and on, but as you can already see it’s not the same for everyone. So before you get a ninja you have to ask yourself. What do I want to achive? Do I want to progress further in PvE? Do I want to get the edge in PvP? Then look at the ninjas and pick what suits you best.
