I'm right now rerunning some low and mid level quests. I tend to take a cleric or favored soul hireling along when playing alone.
In some of those quests enemy casters summon flaming spheres. Now I noticed that the hireling starts to waste spell points on flaming spheres (on "active" and "defend" mode). Not only on healing spells to heal itself / party members, but also uses offensive spells on the spheres.
This seems like a waste. The hirelings will spend way too many spell points this way. If the hireling isn't smart enough to use a simple dispel magic then it would be best if it ignores this specific summon (or simply cast a resist energy(fire)).
