Riot PLS no +10% CDR on Supportitems

As a suppportplayer I have to say : DON'T DO IT! I already have to much CDR when playing Lulu or Karma (not recently cause they are not that strong but CDR stays the same) because 10% / + 10% + 10% + 10% / is already 40%... It even gets worse if u want to build or because I don't want to build to much CDR that is wasted. I think it would be better to wait for that till preseason because of that rune that converts CDR to DMG if u hit the cap. Or u could change so it gives like 29% stats as bonus but no CDR.
