For those of you whom aren't quite as familiar with the game as others, it almost goes without saying that the game is an incredibly difficult and frustrating one when first starting. This is due both to the challenge of the game, as well as the fact that high level players make new accounts merely for the sake of their own amusement (otherwise known as smurfing); and trust me, it can be a royal pain.
In first starting, be sure to play against bots and look up several starter and more in-depth guides on various League of Legends websites (with my personal favorite being
http://solomid.net) as you begin to familiarize yourself with the game. Also, another piece of advice I can give is to never constrict yourself to a single champion (or lane for that matter). Not only does this offer a chance to experience various diverse elements of the game, but it also provides a broader pool of options to focus on upon hitting the max level (being 30).
League of Legends has its own bumps and frustrations, but it's most definitely a rewarding one once you learn the ropes. On that note, if anyone wants to play a game or two sometime, feel free to let me know!
