Ziggs' E needs some work

I love what Riot has been doing with Ziggs so far, like the changes to his W making him a split-pushing maniac and also reducing its CD allowing him to have his disengage sooner rather than choosing a tower over his life. However, I've noticed his E becomes irrelevant late game. Especially during fights, its burden to set since theres a small delay before it activates. Enemies can continue to run through the minefield before it drops (like a zed running mach speed toward you) and the best I can hope for is 100 damage. If it were like taliyah's E it would serve its purpose of being a zoning ability but also punish the enemy for trying to walk through it if Ziggs could also combo it with his W. This just an idea for a champion I absolutely love playing, hopefully Riot continues to improve on this little guy even if they don't see this.
