The Issue on Leech

What about lower-level priests, like you'd find at, say, an older-style Squid party?

If all Priests have a similar rating, you'll still be able to tell who's training sometimes and who always leeches. It's not like the ideal is to be 100% solo, it's just a way to tell who's leeching more.

& bigger parties still split majority to the person doing the killing, I suspect it never goes below ~30% of the exp gained from your own kills unless you're partying someone significantly more powerful.
