I understand your frustration with this change, but it does seem like your very good advice to the other poster about popping Yellows or using a pool power or something applies pretty much equally to this. Pop a break free, use RoP, Clarion, boost up your defense, etc. I believe the power is supposed to be balanced against tier 3 attacks like Power Burst or Bitter Ice Blast, not against Pets like Gun Drone, since it can't be killed.
