Spheres of power is there a point to fount of life or is it a trap / waste of a talent?

I've been looking through spheres to get familiar with it but no matter how I look at it I can't see a point to fount of life . . .

Fount Of Life

You may store a cure within yourself, allowing you to access that healing as needed throughout the day. You spend a spell point and roll the damage healed as normal, except rather than healing by the given amount, that amount of healing is stored. You may store multiple cures in this manner to increase the amount of stored healing, but you cannot store more healing within you than 10 x your caster level. Stored healing is lost when you rest to recover spell points.

You may draw on this stored healing to heal targets exactly as if using your cure ability, except you do not need to spend a spell point; you may choose the amount of healing granted (to a maximum amount equal to your stored healing), and any healing granted to a target is subtracted from your stored healing

It doesn't seem to have much point to me yes you don't spend a spell point to trigger it but you do to store it so cost wise there's no saving. Action economy wise again no saving as it functions same as cure so your spending the same actions on it. If you don't use it you lose it at the end of the day meaning you can spend a spell point to maybe just lose it. The only benefit is the 10 x caster level allowing a bigger one off heal but your more likely to be doing smaller heals as people get hurt than waiting till you need a big heal or die with a few excpetions. I just can't see a reason why you'd spend a talent on this, am I missing something or is it just a trap?

It allows you to choose exactly how much to heal people, so you don't "overheal" them and waste the extra hit points. Increasing your efficiency in terms of spell points.

For example if someone is only down 3 hit points then normally you wouldn't want to waste a spell point healing them for 1d8+CL hit points. But with fount of life, you could cast a heal, use 3hp of that healing on your friend, and save the rest for the next time someone gets injured.

Thanks. I see so fine control but same action economy. I can see the value where if your heavily investing in healing talents you could be doing 3d8 + 100 that's a lot of wasted healing.

Not same action economy cause if you start the day by using 3 cure to stack them then in combat you can use 1 action to heal the same amount of 3 cure so 3 action

I can see that for a lower investmnet in healing but if as I said you go deeply into it you can be adding 5 times your level as a bonus to d8's of healing. I guess it depends on how soon you heal someone when they get hurt and how much healing they'll need.
