Man, what are you talking about? I loved FFXI. I don't know why you keep bringing it up, though.
Parts of this game needs to die or change? What do you think the last year has been about? What do you think 2.0 is about?
Compare FFXIV now to how it was at launch. The only thing that survived intact was the armoury system. Everything else has been scrapped or rebuilt from scratch (and if it hasn't been yet, it will be in 2.0).
