This is already in the rules. If a condition is received during a creature's action phase of its not resolved until the creature's next action phase.
I found in the supplement (page 4) that stun, etc. are not remooved if recieved from a counter strike or a damage barrier... is there a more generale rule elswhere that would apply to Eye for an eye?
Chapter 4: Actions, Main Rulebook, page 9:
"Exception: If your creature receives a condition during
its Action Phase due to an enemy damage barrier or
counterstrike, if that condition has an “end of Action Phase
effect” it is not resolved until your creature’s next Action
Phase (see “Counterstrike” and “Damage Barriers” on pages
27 and 28). "
