This cant be repeated enough. We players absolutely love it when CCP fix bugs. We stick around when bugs are fixed. Once bugs start accumulating in game and are not getting fixed, we get annoyed. Once a bug that hasnt been fixed in a long time does something to piss us off, we leave to find another game do to the frustration of knowing CCP is aware of the bug but not fixing it.
New and shiny stuff in game is nice. It breaks up the monotony. However, if core elements of game play are broken and not getting fixed, no amount of shiny will keep us here.
Please fix the broken elements of the game before you have to spend 2 to 3 quarters of man hours fixing the bugs because someone at CCP would prefer introducing more shiny into the game with its own set of bugs.
