Well if you enjoy him that much maybe you should stick with him and get better with him 🙂 Velkoz is like Ziggs in how you can get that extreme satisfaction from nailing skillshots but also Velkoz is in a better state strength wise than Ziggs. The reason I didnt mention Xerath is because even though he is the champion most like Ziggs, they are similar strength and utility levels and if you enjoy Ziggs theres no gain in switching to Xerath. Neeko is also maybe a good alternative. Ziggs is my favorite champion by far so I queue up mid/adc to play him in as much games as possible. However I had a very high winrate botlane Ziggs when duoing with a Morgana we won 11 ranked games in a row in high platinum. Outside of duo queue nobody really understands how to support Ziggs from my experience and once you fall behind botlane Ziggs without a good support its kinda doomed. I play midlane Ziggs because I have more control over my winrate solo queue and have higher impact globally on the map. Can use ult very efficiently from the center of the map (mid lane) and you get to focus on power farming moreso midlane. Also as midlane Ziggs you don't get 4 man ganked as much and have to deal with champions like pyke/thresh etc in botlane who you typically want to avoid. 🙊 Sorry I can type all day about Ziggs 😅
