Simply put: It would be a real help if BOFF's would use their gear. Why do they not use Hortas and the like? Why can't they use the special abilities of ground sets? Why do they refuse to use the special devices that add damage to the Jem'hadar weapons?
If the Devs could figure out a way to get the BOFF's to fully utilize their equipment it would really help to make them, and the equipment, more worthwhile. They do not have to use it like an expert strategist, you can work on their AI later, just getting them to use it at all would be a nice start.
