ACN/SMN/SCH for the most part are lazy. Very few are actually good at what they do sadly - The Yellow pet is fine in terms of DPS as well even though it's a tank, but 9/10 they're not manually controlling it to maximize it. The Blue one is the caster DPS and also needs to be manually controlled if you like your mobs not being constantly knocked back. SMNs that uses Ifrit on Ifrit tend to also be lazy and not manually control it so if you rely on the stun lock method that messes it up greatly. (Ifrit is a fine pet but..Garuda has the highest gains overall.)
