You want to fix the SMN pets? Okay, simple.

Change 1: Let us macro pet commands.
Change 2: Replace Ifrit's Radiant Shield with his old Crimson Roar buff from FFXI. Grants an AOE buff to himself and anyone nearby that boosts physical attack by 25% for 15 seconds on a 60 second cooldown. Also give him a stat that grants him a Haste buff every time he Criticals.
Change 3: Give Titan a Convalescence type move that gives him a large buff to heals he receives for 30 seconds and shorten the cooldown on his Earthen Ward to 30 seconds.
