I doubt there are nearly enough people with that specific objection to make a difference to WotC.The term "priest" is problematic, because it ethnocentrically specifies theism in the context of a temple or church. For example, there is a reason why the sages of Jewish "rabbi" and Muslim "imam" avoid term priest. Likewise a nontheistic animistic "shaman" avoids the term priest, as does a Buddhist "monk".
A more multicultural term is "clergy", which is any official religious function, including priest, teacher, psychic, sibling/monk/nun, and so on.
