The dev team should focus more on bug fixing. I am tied of seeing how the list of known ingame issue is getting bigger and bigger after each patch instead of getting smaller.
Should the history teacher at a high school focus more on making sure that all the students are learning math? Each "department" has their job, whether it's a school or a video game company... so there really is no "focus better" because they don't prioritize the cartel market over bugs (like so many people seem to think they do) any more than a school would focus on math over history. The cartel market team does their job. The history teacher does their job. The bug team does their job. The math teacher does their job.
