The Mogwand is perfectly fine if you like it, and shields can slot HP on them which can be situationally useful and some have stats on them you may want (some of the company targes come to mind). Just make sure to carry around magic attack food.

It's best to have both an offensive and defensive weapon on WHM anyway because it's fairly versatile and there have been more battles coming out that are much easier if a WHM is able to put out some damage.
