The Sentinal role doesn't get the credit it deserves. It's an awesome role, it drastically reduces the damage taken and basically turns the character into a decoy that absorbs hits while you do your stuff whether it's heal, buff or debuff.
I love starting tough fights with Prudent Planning (SEN/SYN/SYN), Fang takes hits while Lightning and Hope boost the party up then when I switch to an attack paradigm, the enemy just crumbles.
Signature goes here!
