[Gameplay] Ekko's Q does no damage with 45% CDR

On Ekko, I've been selecting the 45% CDR mastery and achieving the cap by purchasing sheen, morellonomicon and using 10% from runes. When I have maxed Q and achieved the cap, I lose all the damage on my Q on its first trip out after I've used Q once (effectively spamming Q on cool down). This will happen every single time you do it, making Ekko a late game liability once you've hit the cap.

Steps:

1. Max Q.
2. Achieve CDR cap.
3. Use Q first time, it will do full damage both ways.
4. Mash your Q till it comes off cool down. This time it will go through all targets without doing damage the first time (wont proc passive or any buffs) and only do damage on the return trip, effectively halving your damage output.
