SE increased the availability of the combat tier IV materia so much, why not crafting/gathering?

I was really hoping SE would make it somehow easier to acquire them since you now need them more than ever to reach the three star requirements, all this while keeping the Tier V as an "special goblin lottery" reward. But for some reason, tier IVs are still hard to get for DoH and L.

Is there any way to get enough of them to fully meld our equipement without going broke?? :/
