"Champion" sees no competitive play; we need to do "This" to fix them
But I play that champion, and I'm a competitive person :(
Just because your champion may not be be in LCS games doesn't mean they are bad, or they need some crazy buff so they will be an automatic pick or ban.
Choose a champions that fits your style, that makes you happy to play them, where you will enjoy the game win or loss with them. Even though we all enjoy winning ;)
Don't pick a champion just because they are the buffed flavor of the month, or that you want them to be op.
If you see your favorite team or player in LCS not playing your champion of choice that doesn't mean they are gone and forgotten. I still have love for my Leona, Vel'koz, Sona Supports. I still choose Ashe far before her rework ( simply because cross map arrows are hilarious to me) And I will still occasionally mid Lane Karthus because press R to win. I don't think any of these champions are weak or need Riot to address them for buffs or reworks.
Have fun with the game!
