Using AST's Expand in Light Party Duties

[Arrius]

I don't get this whole laziness angle you are coming from. I already said bole is optional to drop because it is situational [...].

Why is Bole optional to drop, when you just can play it out on the tank at any given time? It's a 20% damage reduction - A free rampart for them.
Less damage on the tank means less healing needed, less healing means more breathing room for other things to do. Like doing damage, for example.

My topic wasn't about expand vs extend - I mere commented that many astrologians I ran across as I level up all my combat jobs simply use expand on every card they get and I do not believe that's the best way to get the most out their cards.
And cards will go to waste, mind you. They often will, even without the use of extend. That, also, is something Astrologians need to think about as well when they choose to play their buffs.

When you got a boss fight going, then there is nothing to hold you back burning Spear and apply Time Dilation and Celestial Opposition on a single target for maximum effect.
