Sometimes I use cure/healing (Cleanse by Fire/Close Wounds) when I don't want to wait few secs for cure/healing with skills. But I could use potions in such situations. Sometimes I use fury to refresh stamina. But I could use potions as well. Often I use "recall" (Sacred Journey). But I could use charges from my runebook. Very rare I use remove cursed. And very rare I use enemy of one. I could live without them. So it seems that chivalry are wasted points for a warrior (melee or archer).
