A lot of people hate the fact that people play free champions in ranked with no prior experience. A lot of other people say that they just want to practice to see if they like certain champions before investing in them.
So, in response to the thread from RiotChris asking opinions on the matter (About half and half for Y/N atm), I propose an easy solution.
From now on, during Free Champion Weekends, you can only use the free champions in Normal and Practice games. For ranked games, you must own the champion or have it be on the weekly rotation.
So now if you truly want to try out champions, then go ahead, have a blast in normal or practice games. But, please, have some decent experience with champions before going headfirst into Ranked.
Little Note - This isn't my idea, it's just no one has made a thread proposing it to Riot. I simply believe it's a great idea and would like to help get it out there.
Edit to this little note - Yeah so someone just made a thread about this the same time I did. Whatever >.<
