Overloaded abilities aren't always a bad thing tbh
Look at Lee Sin, Lulu, etc. They're pretty overloaded, but they were made right where it's not a bad thing.
Darius's E is overloaded with armor pen, but this is to add power into him without adding so much. Since you're maxing E second or last.
Now there are some bad overloaded abilities, but overloaded abilities aren't always a bad thing.
Should stop acting like they are.
