if you're miffed because you can't participate in hextech rewards because of your one slip-up...
then improve your in-game attitude and eventually you'll get your free stuff. if you're in line for free ice cream, and you start kicking people, of course you'll get sent to the back of the line but at least you're still in line! keep kicking people and you'll never get free ice cream. it's not a permanent suspension from hectecch crafting
