What’s the point of Physick for Summoner?

[Exodus-E]

I personally, would like a level 30 Trait that changes Psychic into a instant 500 potency heal. And during Phoenix phase it's potency is increased by 600. Of course that probably means having Rekindle do something else.

Unless they finally adjust SMN's Physick so it scales with INT (like RDM's Vercure), those changes are completely useless.
Until then, replacing it with Rekindle through a Trait would be the most "sensible" choice.
