Should Zoe's Paddle Star be changed to not deal all its damage at once?

Pro play has made it clear that Zoe's instakill Paddle Stars are kinda broken. It's especially notable since, over the past two years, Riot has actively removed various Champions' ability to OHKO opponents without either using their whole kit, without it taking more than 1 second, or without it requiring some severe risk (i.e. Leblanc, Talon, Fizz, etc). But then we get Zoe, who just has to use Q+R properly and can basically instakill with little-to-no ability to react. And before you say "it's hard to pull that off", that's what people said about Nidalee's nuclear spears.

I'd personally like to see Zoe's Q changed in one of two ways (mutually exclusive):

• Paddle Star deals half its damage immediately and half over time.

OR

• Paddle Star deals damage and applies a mark to enemy Champions it hits. Attacking a marked Champion deals bonus damage. (Adjust as needed)

Because being able to OHKO an enemy with just 1-2 abilities is wrong.
