So, for my sage, let's say I would want it to eventually to become a Battle Mage. Let's say I would want the following abilities:
Sol	(Hero) <Assuming I change the archer reclass to fighter/merc> Lv. 5
Ignis	(Battle Mage) Lv. 5
Maelstrom (Battle Mage) Lv. 15
Soothing Hand	(Valkyrie) / Slow Burn (Dark Flier) Lv. 5
Dual Support	(Valkyrie). Lv. 15

Is that too many reclassing?
