I suppose the way I worded my issue with it wrong......<br/><br/>My issue isn't that she has the Mirror Ring system....my issue is that a feature like this is being given out so freely........I guess in a sense I just don't like how the authors/ script writers are at liberty to use this as a stop gap to make dramatic tension and could potentially become too over used thus making the "Ultimate Defense" value of it go down because the more it is used the more likely it is that it will be made useless by someone figuring out how to force it's use and then take advantage of it's cool down time to easily kill of the character using it.<br/><br/>As for Hyuuga and Kongou not using it since they are both Flagship Level Battleships well to put it simply I have no idea.
