Mastery and Runepage Help

You'll find the link to my Masteries and Runepages up there ^.

So I've been wondering about the set-up of my Mastery and Runepages. I think they're alright for the most part, but since I'm getting up there in IP again (around 3000) I'm wondering if there are some Runes I should buy to improve my pages or if I should save to buy some more champions (IE: Rek'sai, Wukong).

When I play, I generally want to play (in order) Mid > ADC > Support > Jungle > Top. For the champions I prefer to play;

Mid - Leblanc, Vel'koz (sometimes Fiora or Riven) ADC - Varus, Kalista Support - Leona, Zyra Jungle - Jarvan IV, Shyvana Top - Riven, Irelia (sometimes Fiora)
