• Severity: Makes a feature of my app completely unusable

Repro Steps

1. Play a practice tool game
2. Buy any item with ability haste or use any rune that adds ability haste
3. query the live client data api
4. the api returns active_player.championStats.cooldownReduction : 0

Thanks for this report. I've escalated it to the team.

A fix for this is in patch 11.5 which should be live on March 3rd. We've added a field called abilityHaste and cooldownReduction still returns 0. In patch 11.6, March 17thish, cooldownReduction will be removed from the response. You can view the changes that will go live in 11.5 on the PBE right now.

{
  "championStats": {
    "abilityHaste": 8,
    "cooldownReduction": 0,
    ...
  }
  ...
}

The removal of the cooldownReduction stat has been pushed back to patch 11.7, roughly March 31st.
