I usually convert them into more action posed figures.
However, Mithril's major market (and Mithril's license) is for collectors and diorama models. So Mithrils tend to make more sense in dioramas. Note the difference between the war-like poses of the Corsairs and corsairs by another company. The other company does kinda generic poses; Mithril Corsairs make a lot of sense standing together, and interacting.
