I may be a bit biased here, due to the fact I've known him and staffed for him for years plus the fact I'm currently his Voice. But I want to state that, before Riddick became Emperor, any devastators he had were agreed upon by Shepard. His crystal was neerfed into the ground after complaints flooded in and it now does the same damage as a regular artifact with no other buffs other than looks (That being the chainsaw blade), and apparently Shepard is still getting complaints about it for whatever reason. I completely understand your point of view and I get why you have this opinion, but being his voice, I'd like to state that he has made a choice to be serious as Emperor and be serious as a player.
