Thus, I don't see any valid reason why only one aspect of the game - in this case fighting - should get much more attention than the others. If you want a rather complicated fighting system (in the opinion of those who don't want that), I do want a more complex magic or trading or dialogue system. I think I can talk better than fight... so, I want to use that in the game to have more success and eventually more fun.

I would want the magic, trading and dialogue system to be more complex as well.
But when thinking about the last RPGs I played, I have to come to the same conclusion as before.
If the developpers think fighting is that important, they should work it out further. In the last RPGs I played it really bothered me. (much more as the simple dialogue or trading systems bothered me)

There is no spoon !
