Also take my message with a grain of salt since I'm only lvl 32 and learned most of this through in-game experimentation.
It also seems that once a mob breaks charm ~3-4 times they break charm a lot more often afterwards. Not sure if this is just a placebo but I usually make sure to kill them at this point. In groups pets don't consume exp I believe, so I generally try to keep my charm pets alive there.
