Understood, but if her desired character concept is "to turn into a bear or other big beast and eat faces" then closing the gap is required, and tactics will have to match.
I don't think anyone is saying that it will be "optimal", but it's more than possible in my experience.
My wife plays a similar character, but she picked up an Animal companion as well.
She generally opens by either shifting and closing the gap, or sending in the companion, and then shifting in anticipation of joining her companion in melee on the next turn.
She can and has hung back and slung electric arcs as well, but that does not fit her class fantasy, so she doesn't do so usually.
Is that always "optimal"?
Nope, but it doesn't get her or the party killed, and she's having fun and contributing.
