When to DODGE
After over a hundred games I have noticed patterns. Dodge in low ELO whenever you see any on your team: Yasuo Ahri Riven Lee Sin Aatrox Sion Nasus

I wouldn't say Nasus or Ahri are quite on the level of those other champions. What's gonna happen, is Nasus not going to be able to press Q, and is Ahri not able to do a combo (which they should be able to do if they intend to choose her in Ranked)? The others have a bigger room for error since they have a massive chance of causing a flop when they try anything. And why not include someone like Gangplank, if you're including Nasus?
Then again it's also entirely likely for a low ELO player to get crushed regardless of who they pick.

Whenever a skillshot is coming towards you obviously
Well, I have a 65% winrate on my Sion in Bronze, but if you don't want the win, ok, dodge, i don't care.
