Have to disagree. On top of the spirit bond changes that get you a ton of DoH/DoL materia if you do it regularly, getting scripts is suuupppeeerrr easy to do. I believe I casually got 4000 white scripts in like an hour the other day from crafting collectibles.

you mention that there should be more sources for non combat materia, what sources would you suggest? I'm looking at the obvious here but you would need to craft to get crafter materia so not sure what else to do beside what is already implemented. for gatherer materia I could see them adding VII and VIII materia to timed nodes to be collected like the 80 maps (only able to get 1 every 18Hrs). Idk but there are a few more options for DoL than DoH.
