I think this adjustment to Meteor is a really good example of the right kind of power-reducing adjustment.

It doesn't make the spell worse across every situation. It doesn't affect the spell at all in most situations, actually, since even six Black Mages is a lot to bring to something. This change only affects the situations where 3+ Meteors would have been steam-rolling over content.

The one thing that the Development Bros thought was improper has been changed and everything else has been left well-enough alone. This gives me joy.
