User blog comment:GutsyTick/CP: New Items and an Ekko Rework/@comment-4636093-20151121004344

Actually, 3 hits DO belong on every single champion which can feasibly make use of it.

It's both an interesting and effective way of balancing what would be incredibly powerful effects, allowing Riot to finetune so many different aspects of the ability.

As for the rework here, it's not too hard to land both hits of Q, simply increasing the damage it deals to a massive 300(100%AP) would make the skill obnoxious to play against.

The W without the stun isn't good enough to actually waste mana casting as a shield after a 4 second delay removes the playmaking potential of the skill.

And Riot alreay said that they tried to have Ekko's ult do that, however it turned out that it gave Ekko no control over what it actually did, in 40% of the time it did nothing useful and in 60% of the time it actually hindered him.
