PLEASE Read the Preseason Patch Notes

You don't even have to read all the bad jokes Scarizard keeps putting in there or all the essays he keeps writing. Just look at the actual changes and keep in mind what they are.

I always get maximum triggered when people are asking in-game what their champions do now, then proceed to build the worst possible things on them to then declare that the champion is underpowered, just because they didn't prepare to play them properly.

Take the 20 minutes and read up on what is happening. It'll be worth it, you'll be playing much better if you do.
