No matter how you cut it, Astrologian is on par with White Mage and Scholar. The buffs they have, all have their own effect and place, so you cant really compare them to White Mage or Scholar, and vice versa. Its not that they have stronger shields that makes them more powerful than Scholar, or the fact that Astrologians have the same potency heals as a White Mage so they can burst heal almost the same; Astrologian was just made to be close to equal as possible. So lets cut the bullshit with AST v SCH v WHM. All three of them are now equal

-Sincerely, someone who has WHM SCH AST leveled and tried all three in A1s.
