So basically, you don't want it to be addressed to a certain person or group, but you don't want it to be addressed to everyone?
* Draco Tanos golf-claps.
Yes, Draco: he wants it to be addressed generally, asking that
someone or some few change, not that
everyone who can change.
The latter is asking that particular people change their class, too.
It should, in fact, be addressed
indeterminately. That's sort of the point: so that no particular person feels that they, specifically, have to do it.
