Example:
PLD Level 70, requires 2.9 mil exp for next level
DRG Level 73, requires 3.3 mil exp
SGE Level 78, requires 4.77mil exp
Sch Level 80, 5.9mil

Scaleable quest in Raktika Greatwoods
PLD reward 54k
DRG reward 55k
SGE reward 56.8k
SCH 57.2k

That hardly seems like proper scaling on ShB content does it... Pretty useless for levelling alt jobs.
Checked SGE in Ondo Cups and same exp for these "Scaleable" quests...

Were alt quests always this miserable for exp? I would like to do something other than grind FATE/Bozja or re-run dungeons but at the rate you accumulate xp doing side quests it would take a week to do what can be done in 2-3 days doing fates/dungeons.
