Yes, we have noticed this effect as well. Other way to deal with it is to remember to use less charged shots. The benefit is that you can "speed run" it with a friend pretty easily. Nice in AXCZ when there are more worthy targets waiting.In fact, they are so powerful, this can actually become a liability; on the last heart of a cyclops, four fully charged shots will instantly cause a panic Shield every time. The easy solution is just to have a separate Fire Group where I only fire one or two at a time.
