Yep. My pierce wizard was a fun project too, even if not the most damaging but I just like how it can go through all the enemies and wipe em clean like that. Abusing 50% pierce dmg from hero points per enemies + Frozen and other stuff. Guidedshot is also great with that and other piercing skills with 50% dmg per pierced on hero points.
Also just skills that naturally pierce in general or adding 50% -100% pierce chance so any skill can Pierce (piercing wand barrage, so good).
