Why is ziggs ultimate not global?

cause that would be broken af. idk when you started playing but long before the mage rework ziggs was a busted wave clear champ that could stall a game till 60 min easy partly cause of the ult just throwing it to a pushing lane and 1 shotting every minion and using bombs to clear another wave. at a higher lvl its not justed used to snipe someone at low hp its used a lot more for the pressure it can provide and if it was global you could 5 man bot vs the other teams 4 while they have there top pushing top side and if ziggs was global just chuck up the bomb and completely negate what the other top was doing.

He should scream "allahu akbar" as well.
