So, I'm contemplating AGAIN, using the LoL wiki for the role/attribute determinerer because some of the roles and attributes I highly agree with based on my experience playing the game. I wasn't trying to say that I didn't see Riven as being an assassin because I most certainly played her like that when I used her lol...hm...because I was looking at what it said for Garen and yes, I would say his secondary role would be a tank, especially in situations where a real tank would be  absent.<br/><br/>The wiki also has the characters' last names lol.
