The Main Ziggs Changes a Ziggs Main Wants

Ziggs was one of my first 6300 champions. I've played him for years. He is currently the only champ I'm mastery level 6 on and I'm working towards 7. There's one thing that's always bugged me though, so I'm just going to throw out an idea to fix, and then a couple other ideas I've had.

First: Zigg's's passive shouldn't get used when your target dies while your auto attack is in the air. That's an awkwardly worded sentence, but basically there's nothing on Ziggs I hate more in laning phase than wasting my passive on a minion that dies before I hit it, but hey, maybe I'm just bad at farming. It would still be nice to have my passive up to poke my opponent after I fail at last hitting to bring some balance back to my lane. This is really just a quality of life change. It would make farming more forgiving while not pushing him into OP territory.

The second change I want helps both his laning phase and his strength in teamfights. It would be nice if Ziggs auto attacked just a little quicker when he used his passive. Just like 20 percent or something. This would make him better in duels, which I've died in so many times just because I wasn't able to get one last auto attack off. Seriously, it would help his burst so much, like passive E R Q W passive or something. I don't know, I'm not much of a theory crafter. I just know this change would make his gameplay feel to me like it was flowing better.

Finally, and admittedly the least likely AND least necessary change I want: a global ult. Ziggs's ult is already hard to land at max range, but if it was global it would be more rewarding while also raising the skill ceiling. It might as well be a global. It would make blind baron or dragon steals right after reviving a viable option. They nerfed the damage to minions recently anyway so it wouldn't always be used to save a turret from across the map. Gangplank's ult (my second most played champion ironically) is still global even after the rework, and God bless you Riot, but it's instacast which means it's technically more OP than Ziggs's ult, even if the damage is weaker. It even slows.

While I'm at it, the W change where it can execute turrets has only been mildly useful to me. I don't use it in laning phase because I want to deny my opponent CS, and later in the game if a turret gets low enough it's usually because the rest of your team is rushing it down after a team fight. Same thing with sieging. Getting a turret that low usually means you're in a position to take it soon after. As far as Ziggs W changes go, the one where you can queue up the explosion midair was definitely a more impactful one.

TL;DR Please don't let passive get used when target dies before it reaches it, slightly faster AS for that attack would be nice, global ult maybe? Also, W buff kind of sucks.
