Well, now that we are back on the original topic, I have to say that I agree.

I was once in the position of asking someone who only had BLM RDM and WAR levelled to come on BLM to proc yellow staggers but it turned out she was missing several tier 4 spells. This happened even after the third Abyssea add on had been released. I had even told her before she came out that she was needed to proc yellow. I was especially disgusted because she had had BLM at 75 long before the first Abyssea expansion. Her excuse was that the spells never dropped when she tried to farm her (which I replied she should just buy them then). I never invited her along again.
