Yeah sasuke over kakashi; kakashi too squisy and i feel sasuke has some give; plus he brings a field change as an added to your iruka interupt which will also buff your hinata. I still run my Iruka at L72 and 22.5k BP He brings decent tankiess and buffs/shields an interupt and the ability to dodge and be a troll(Not very likely bt it happens) Losing him doesn't affect my combos. I know he'll fall off eventually and soon which is why I'll replace him with sage naruto or when we get kage treasure.

What summon are you using and have?

Seems pretty solid for now; just remember to move your combo around since with hinatas chase on knockdowns she acupuncture it'll help you to CC the entire team and lock them down from using abilities.
