A functional Light Spirit would allow you to at dire situations call it out and basically add a WHM to the alliance. Bringing a WHM might have been overkill to start with, but bad luck made it a necessity. SMN simply covered it. (Or PUP, if you wanted to use that as a backup WHM solution).
A functional Light Spirit also allows you to change sub. If you can cure yourself, you can sub for example SAM and meditate TP to fill in WS triggers in VW. Or you can trigger NMs in Abyssea. Or you can simply refill MP with Myrkr if you happen to have that. I tend to sub WHM for cure IV. If I had Cure V from a trusty Light Spirit, I'd sub SCH to help nuke trigger on VW.
Other spirits have much less use. A split casting timer update like for PUP would allow them to be used as debuffers and DoTers, instead of Avatar spike damage. An obvious use would be triggers of course. But else it is mainly to avoid amnesia on an avatar, while making yourself vulnerable to silence on a spirit.
Another way to view spirits and avatars, are that avatars are for bosses and spirits are for normal mobs. After all, if a monster dies in 10 seconds, then a spirit casting nukes every 20 seconds is better than an avatar who does BPs every 45 seconds. Spirits are not meant to replace Avatars, just fill in those gaps the job has where you are just standing there watching all the BLMs, WARs etc kill monster after monster while your BP timer is ticking down.
(Best would be if spirits had -ga magic, but I doubt that would ever happen)
