Can we nerf and buff Ziggs?

Ziggs is currently at 54 % winrate (champion.gg). However, his Q still is almost impossible to hit in a 1v1 outside the first bounce, which means you practically always use it for waveclear. If enemy mid leaves lane, he just shoves and takes tower FB extremely quickly, which is uninteractive, but wins games. I actually like he has this strength with his new E, but his passive tower shredding is simply waaaay overtuned - later in the game, you dont even demolish towers because you can take them down with 2 passive procs. I suggest these changes

• Don't let him proc his passive on turrets - He is gotta use it for PvP (or farm). He can still blow turrets up with W, so his "tower busting" is still above average

• Revert his bomb hit detection radius from 150 to 180. This basically means he has an easier time hitting bombs on 2nd or 3rd bounce.

This would make Ziggs want to fight his opponents more in skirmishes and 1v1, and not just mindless pushing until the 5v5 fights happen
