They have to continually have arcs where they lead a group. Apocalypse and Magneto regularly have arcs that spanned most of X-Men's run.

I'd say to avoid plot armor let them get hurt and potentially suffer mental or physical trama. It can help develop the character and help prevent the audience from believing they are invincible.
