Balance between SGE and SCH

[rewd]

Its not a flawed logic. Cure 3 is a gcd heal, all healers have gcd heals. You can have an ast spamming helios for the same effect with less efficiency. If bigger shields (shield values that other healer have no access) were mandatory, obviously that would lock sch spot which will never happen. Same with expedience, as only sch has access. its not like other healers have a worse/different version of it.

Why bring other other jobs if someone is always the numerical superior? Because if this numerical difference is small enough than its no biggie, thats why

Not every GCD heal is the same.
Helios: 400 healing potency, 15y radius, 700 MP (on the healer with infinite MP), costs 250 damage potency
Cure III: 600 healing potency, 6y radius, 1500 MP (on the healer with the worst MP economy), costs 310 damage potency.

None of this screams "more efficient" at all.

Yours is indeed a flawed logic. Bigger shields and Expedient are very strong exactly because they are not mandatory. As such, they are an advantage and not a requirement. Why do you think Divine Veil, Shake it off or Passage of Arms are strong skills? Becausethey are not mandatory (nothing is anyway) and represent a clear advantage that give you an easier time in prog/in some strats.

Unless a job is hilariously undertuned (like PLD and DNC at the moment), it doesn't matter. SCH and SGE have both their pros and cons (and they could even be used together to great results, making your point even worse). If and when Chain Stratagem gives SCH higher rDPS, will you be asking for SGE buffs because there is no reason to use it?
