If the Spell Speed bug ever gets addressed I think that SMN single target damage will see a bit of an improvement

Even on current gear the pets are losing ~3-5% Damage. On a heavy Single Target build (CRT/SPD) it would be very noticeable, since you would probably be using Ifrit and have the higher Enhanced Pet proc %.
