Riot's Balancing Team Getting Better, But Still Issues

First of all, most of patch 6.2 was a good patch, but their is still major issues, for some reason they nerf all the top shelf top laners execept fiora , i understand nerfing them all, but why would you keep a top shelf nerfless when you nerf the other ones. And don't get me wrong those champs did need a nerf arguably more than what they received as you can see from my gangplank stats http://na.op.gg/summoner/userName=saltyfrenchfrie I also dont undertsand some moves this balancing team makes as of recent as patch 5.24 giving karthus a nerf of any kind(and i dont even play karthus), and i say that because last time i vsed an actual karthus was probably more than 3 months ago, i dont understand nerfing champs that are hardly played and are already punished for their lack of escapes and mobility as it is. And dont get me started on rageblade, how is this item not been touched the last couple of patches, this item should have been nerfed a patch ago if not sooner. And plus most of the champs that use this are already afk junglers, i mean if im top and i am vsing a jax at least i can delay him from getting this item, but if they are jungler i have no power over this, unless we have a full coordination from our team in dealing with that, which in solo q is unheard of. Also graves not touched, rlly.
