Despite being a support class, if you put a dust bishop on 'hold ground but attack enemy if in range' and you don't give them any movement or attack orders, they won't attack any targets on their turn.

I had the same problem, really annoying. It is possibly due to being a support class, as usually they cuse spells and support, and the dust bishop might be stuck/confused because it has no spells, he buffs by attacking...
