I feel like there was a missed opportunity to touch up Zac's W

I love Zac's new abilities. The new Q is so damn satisfying to actually get off, and being able to dive into the enemy team, grab as many people as possible, and then dive back into your team is SO fun. But I'm kinda disappointed that his W wasn't updated from the "Mash this ability the entire teamfight or your damage / healing is suboptimal" ability that it is.
