Ok, lets do it, WHAT is wrong with this game?

They could do a hell of a lot just by randomising fights a lot more. and moving away from the heavily scripted and predictable stuff we have now.

While I don't necessarily disagree with you, I suggest you take a look at the tantrum people are throwing over Rathalos. It's probably the most "randomized" fight currently in the game what with none of his attacks having ground indicators like most bosses. And people are freaking out over how hard it is. Could you imagine the reaction the devs would have to deal with if they randomized, and therefore upped the difficulty, across the board? I wouldn't personally mind it at all, but I certainly understand why they wouldn't want to do it. It's one of those situations where they are damned if they do and damned if they don't; no matter what they do, part of the playerbase would be angry.

I wouldn't mind if they added harder 4man content in addition to the tiers of content we have now. Something to act as "savage" content for smaller groups. I don't know if they would ever have the budget for such a thing, but it would be a way to cater to both the people who like the more "story mode" of the game and those who want something more challenging.
