When I first got into league, I knew nothing about how to play various (duh) (the difference between bruisers and carries, what CC was, etc.).

I found it incredibly frustrating that I had to learn a little bit at a time, learn more about the game to then continue searching, all on my own (TEH BUTTHURT I HAS IT).

Please include a list of relevant third party websites somewhere accessible to new players (login screen/the play button area?).

Such websites I would recommend include:
lolwiki about general mechanics and item/champion details
mobafire's LOL for build guides
championselect for champion counterpicking
solomid for build guides
elobuff for paid access to better stats about ranked
surrender@20 for LOL rumors

Or you could Google "League of Legends"

Thank you. ^_^

Bump.

I am torn. As a new player, asking questions and just playing will typically help you. I feel like pointing new people towards that much information could result in information overload in general.

Bump.

Agreed. This isn't a run and gun game. You need to know the champions in order to play against them. I really don't understand how a LoL wiki search can lead to information overload. You search for the champ you want to play and pick a guide. It then tells you everything you NEED to know in order to play.

I second this idea. I think implementing more of the community into the client would improve the community. Not just YouTube videos that no one really watches.
