Why is Ziggs so hard to carry with?
I thought it was just me being bad but looking at champion.gg, Ziggs has a pretty poor winrate even over a large number of games. It's barely above 50% and his late game winrate is one of the worst at 46.5%. I think a lot of this is his unreliability and how easy he is to outplay. His ult. takes a long time to land and shows the center quite clearly. His Qs are also quite predictable and have a very small radius.They also don't work like Ahri or Xerath Qs in a line. Instead, they'd just hit the frontline and stop there rather than going through everyone.
So, my conclusion is that his skills either need to hit harder or be more reliabe for him to be a good pick. One way to fix the latter is to have a lot of CC in the comp he's picked (maybe an Amumu, Naut etc.). I've looked on many sites trying to find a Challenger or Masters Ziggs main with a 60%+ winrate over 100+ games in any of the big regions and have failed. He isn't a generalist pick like I first thought and is probably still a bit lackluster compared to Viktor Ahri, Malz etc.
Am I wrong and if so, who can I look to emulate? I enjoy playing Ziggs but my results are bad.
