If I was in charge of it I'd definitely just throw away the entire current system and redo it with the idea of making it enjoyable and well-implemented. Not going into it's conception with the idea of making it as stupidly brutal as possible because I can't produce quality content at a reasonable pace, while also using almost no developing resources at all by adding almost nothing new to the game. I'd probably add some cool boss arena fights like hydra, some group and a few solo battles based on the job. Because you never see anyone say "Oh man, I hate fighting BA monsters." Ever. Add in some cool cutscenes in between and boom, it's already way better than the current crappy thing they've got going. Might be more work, and I doubt it'd take people 6 months to do or whatever. But I bet people would at least enjoy it and look forward to the new upgrades instead of hating it and dreading whatever horrible crap they're going to be made to do next.
