Yea, its probably a condition with jamab's strobe following function. How are you setting follow between the characters? Do you have 'Pause Strobe During Combat' options enables, not sure exactly the naming. I have a similar issue with my Shaman/Paladin set, post-combat my shaman will be tossing a Lesser Healing Wave to top off the paladin and the follow pulse hits and she walks out of the heal (interupts).
