the auto is tricky if u don't know how its works, its start from pos 4 to 1. then its checked if pos 4 to 1 there are a "prompt" mystery or not and cakra value. so its mean on round 2 if you have a 20 cakra mystery ninja or 40 that are a prompt mystery then your pos 1 and 2 will not used their mystery. and a barrier 1st round like no 2 priority while mystery like iruka/neji is no 1. so when u put 2 ninja with 1st round between sasuke barrier and iruka mystery 100% iruka will use his mystery 1st since its a prompt interrupt. while a prompt skill like hinata seem be less prioritized than a barrier type.

i do build a team base on this calculation and can leave auto on almost (PVE and some low PVP) every battle but there are some back draw about this trick is, it still use the lame AI to targeting. but yeah still better than a potato line up.
