We discussed this one heavily with the smite pro players and came to a few important conclusions.
this trick is not hard to do. It's simply a knowledge gate. As long as you know it exists you can use it.
it was rarely used on players , so you could say that's the skill element, but mostly this just gave Terra far better lane and jungle clear than intended.
the character is most likely going to still be comp viable even with this nerf
In addition to those points, I also designed this goddess and I consider this effect specifically against her design intent. The stones are essentially consumables and players have to choose which option they want. Being able to have both invalidates that.
It seems like there's a good bit of discussion on this one but I would not expect to ever bring this back on Terra.
