RIOT, Please never rework Ziggs
He's my favorite mid and a ton of fun even if he's not good into a lot of matchups like Yasuo, Kassadin, Ahri, Fizz or Talon/Zed. His late game winrate isn't very good and I know he's barely ever picked in Masters+ but I always feel useful somehow (even if I'm not carrying) and his abilities can be used in so many different ways. I can find a dozen different uses for his W combod with my abilities. He's not picked a ton because he's not flashy like a Malzahar flash ulting or a Zed outplay and is also quite unreliable but that doesn't mean he needs to be reworked! I also love his personality and laugh. Some champions will just be niche for whatever reason and that's just fine.
I am terrified that the mid I find most fun now will be reworked like happened to my AP Kog (ruined now) and Xerath (clunky kit with weird charge up times, less damage and a slow zoomout so I can't even use ult. quickly - I know some like him a lot but it's not what he used to be). So many champions I enjoy have been imo made much less fun due to reworks. They're basically different champions completely. Xerath's kit for example feels NOTHING like before. His skills were all very responsive and higher scaling even if he had less range/cc.
One of the few reworks which I actually thought was less reliable but more fun was Zilean. I think his skill cap is quite high now and the rework was overall very cool. Brand's wasn't bad either. However, please stop reworking champions in a way that destroys their identity and makes their feel totally different. I am actually so scared to even buy more Ziggs skins because I fear he'll randomly be reworked. This is a big part of why I won't be touching Ryze any time soon either. Just as soon as I learn Ryze's kit and find him fun, he has a different kit or is awful and in line for a rework. Reworks are interesting but do them only if really necessary or because it's exactly the same playstyle but more interesting (Kat was a good one)!
