If you see a champion do well, that does not mean they are over powered.
This is something I wish everybody accepted and understood. Every single champion is able to carry a game. If somebody does really well with a champion, maybe an off meta build or odd playstyle, that also does not mean that it is the new meta or OP. Understand that one case does not represent the actual picture.
That's not to say that a champion that does well in your game isn't really good right now, I'd go check some sites like OP.GG (make sure to look at pickrate too). But please, before you make posts, or complain, or make comments, look up some stuff real quick in another tab to make sure it wasn't just some one trick pony who knew the match up extremely well. If you take about 20 seconds to look up stats, it can make your posts and comments 100% better conversation and makes a lot of peoples' lives easier.
Thanks and happy roflstomping.
