The torps seem to be behaving as always "Escort Pimpslaping", however the and suddenly Kaboom moments are probably showing up now more due to the fact that the AI got a much needed overhaul and actually use maybe 2 skills during the course of their fight compared to 1 or none. The trick is sometimes these skills are things like attack pattern X or I swear I have seen cubes fire off go down fighting. Those skills boost based on % for a few of them so you get NPC damage mod + % boost on that number, and the rather annoying torp is now transformed into the ender of worlds torp.

With any luck one of the season 8 or 9 parts will be revamping how the AI fights and get rid of that damage mod, it scales terribly.
