I guess more specifically since /kisscheck is reporting no problems. My mage will cast the 105 rampage pet (remorseless servant), but not bolt/spear of molten shieldstone (new fire nukes). Shaman will cast sluggishness (upgrade to fatigue), but not talisman of the leopard.
Kissassist reports that it is casting them, but shows Casting ____ as AA (or whatever, with /debug on) and never casts anything.
