Attention AST: Lightspeed is one of your better spells, not a bad spell.

I raid. I've completed T13 on sch. Doesn't change my stance on Light Speed. Casting Stone Skin while moving is situational, maybe prior echo T13 or even T9 before we started to overgear but it's all survivable if your sch isn't a waste of slot.

Lustrate doesn't have a GCD when you use it, you can spam all three shots quickly to bring them back. Light Speed doesn't remove the GCD between spell usage which is bad design and makes it useless in emergency.

It costs the same MP and we have to wait at a normal amount to use it. Lowered MP cost and Lowered GCD would benefit - removing the 25% decrease in heals / dmg would also make it more appealing than a multi-use stoneskin swiftcast. Even raising a raid, still gotta wait for that GCD on raise to use it again and by then the timer for LS will be done.
