Text on materia catalysts a bit misleading?

Just a few usability thoughts...

So, there's a note on catalyst items that says:

[A materia catalyst used with equipment for levels x-y.]

But isn't the catalyst used dependent on the materia you're melding, not the equipment's level? Also, this has the vague implication that the materia that uses this catalyst can only be used on gear levels x-y (one of my friends thought for a long time you couldn't use tier I materia on a level 41 item).

Ideally, I think this would say something like "A catalyst used with tier I materia." Doing something like "A catalyst used with materia for levels 1-30." still has the "can't use low materia on high level equipment" implication.

If you wanted to be *totally* explicit about this, you might also modify materia's text to say something like "Used with equipment level x~" instead of just "Materia Level x~".

Perhaps just throw the word certain in there. Something like...

"A materia catalyst used with certain equipment of levels x~y."
