I'm thinking of doing a 'Did you know...' series of posts with little tips for newer players.
If any new or lower rank players would be interested, just let me know and also make note of any particular Champion Roles or Champions that you have issues playing as or against.
E.g. If a Rengar Ults and you're playing something that should peel and have a Disable on your Basic Attacks (i.e. Udyr or Blitz), you can stand right next to the carry you expect the Rengar to jump on and Shift+Click to move so that you'll Automatically hit him with a Basic attack when he reveals himself. The same can be done for any other assassin who wants to dive onto your carry such as Akali or Zed. If you shift+click to move, they'll get stunned as soon as they come into range of you.
