Getting back different tier spells?

[Firon]

Depends. In Abyssea tier III > IV > aga (aoe tiers) were used heavily. In Voidwatch all tiers are used. WHM/SCH/RDM curing will use III/IV/V/VI depending on situation. BLUs will use different tier debuffs depending on situation. While leveling you'll use different tiers as it is what's available to you at the time and so on.

This game can use tier spells even if they scale, because Cure > Cura > Curaga isn't really enough cure spells when you think long term, breaking it up to Cure > Cura > Cura II then Curaga > Curasa for AoE tiers work fine. While Curaga works on less hp > more healed, it's really an "oh shit" spell since the only optimal cure spell will generally be locked down on recast whereas if we had multiple you could cycle through it incase of emergences (since most encounters you only have 1 benediction.)

The bold makes no sense seeing how spells scale with your lvl meaning that Cure will always be a effective spell at all levels means it better long term then lets say XI where cure 1 is pointless in anything but PL.
