When using the “Flying Kick” power, it has a 5s cooldown, i tested building into 45% cooldown & his flying kick remained as a 5s cooldown.
Zenyatta’s Discord Orb target cooldown does not get reduced either, which seems a bit unfair, considering kiriko can tp every 3-4s to remove orb herself & cleanse the team every 6s, zarya can just place bubbles to cleanse, mei can cryo-freeze & place ice wall for allies, reaper can tp or wraith, moira can fade (her team can too with a power), Thats 5 out of 21 characters that can cleanse themself or the team (23.8% of the roster can cleanse orb & do so frequently, especially with cooldown builds, which i’ve seen kirikos running a lot).
Not to mention mercy can increase dmg amp from 30 to 35% then put that on another ally with a power at 50% reduced effectiveness, meanwhile zen keeps his discord orb cooldown of 6s & LOS removal after 1.5s as well as jump kicks 5s cooldown.
