Is it worth noobs getting involved with this game now?

The game, itself, is fairly fun but the community is horrid. I loathe the league community with a passion and it only seems to get worse the longer you play. I've been playing since season 2 and I still go back every now and then. All I can say is mute mute mute mute mute. Just mute everyone and everything unless it's your friends because 9 out of 10 games will end in flame once you get higher level and start playing different game modes. Smurfs are ever present in the lower ranks so you can expect to be stomped fairly early and it won't generally ease up until you start getting skilled at the game. I, personally, would look up tutorials on the free rotation champs so you get a better understanding of what is required as well.
