mana restoration mastery or Meditate change suggestion

instead increasing your mana regeneration you should get mana per killing units

Either it's Meditate change or new mastery that is focused on farming restores 1 / 1.5 / 2 / 2.5 / 3 mana per minions / monster kill

It's really irritating how some mid laners seems to have infinity mana sustain while they are harassing you with their abilities

They get Doran Ring that gives them mana per unit kill but instead focus on farming they use their abilities for infinitely harassing you over and over again and it feels like they don't lose any mana. Meanwhile some champions who try to farm kinda lacks of mana. So with change it will reduce the frustration against infinity mana champions and will give champions better sustain while farming
