Just a little reminder to everyone complaining about "OP champs"
There is NOTHING restricting you from playing that champ. If Vayne / Darius / Garen / Veigar / Gnar etc etc is so r%%%%%edly OP THEN PLAY THAT CHAMP YOURSELF! Riot doesn't care if you cry about a champion on the forums. Take the time you used to complain and instead learn said champ, or even better, learn how to counter said champ. Every champ has a counter!
edit: And yes, I know "having to buy champs is a restriction" but it's not difficult to save up your IP for certain champs. Use common sense.
