I am the author of three lovely niche builds, one of which is a guide to everything an aspiring Blitzcrank needs to know, and two Twisted Treeline builds for underplayed champions.
I personally favor Twisted Treeline for playing, but I play Summoners Rift just as well. If you wish to play a game with me, feel free to message me in game.
I am also available for questions (I am an active theory crafter and therefor are up to date about all viable champions, champion builds and the current metagame) on MOBAfire through the PM system.
Good luck and have fun with your League of Legends career!
