there is one thing i don't understand... attacker keeps the chain going and wizard make the chain increase quickly,assuming there is an enemy with a really short bar,can't i just make a team of 3 wizard and go to town or heck use 1 attacker and 2 wizard and then switch to 3 wizard?
also should i worry about 5-star every boss fight?
I don't think so,never cared about stars though
You can make a team of three wizards,but the bar will go fast down then.You need an attacker just to trigger the slow chain after that wizards will do the rest.
The problem is that later in the game you will need to heal,enemies will become stronger
Not sure how far you are but game will introduce something called "paradigm shift"...it will allow you to change "jobs,roles" on the fly...you can predetermine them in the menu
Powerful enemy
Enter as sentinel,healer,attacker
use them
paradigm shift
wizard,wizard,wizard
bar is gone...if enemy attacks are too powerful replace one wizard with a healer
paradigm shift
sentinel,healer,attacker
repeat
