I've been looking for a tank to play, as I've been normally playing AD and AP ranged carries. I've started to move more into the melee aspect when I played Irelia during her free week (and Riot, if you're reading this, when you do change her just keep her a bruiser/fighter, she really isn't an assassin at her core as of now). I've never really played a support character like Janna or Zilean, but I am interested in getting to know a tank.
Now, Shen has a reputation for being one of, if not the most, amazing tank in the game. He also has a reputation for being banned a lot, and this last patch saw some substantial nerfs to his early game burst potential.
So, I ask the League of Legends community, and more specifically Shen players, how does Shen fare post-patch? Is he worth the IP, or should I look elsewhere? And if he is still good, what advice would you give to a new Shen player?
