When to teamfight

Teamfighting when you're alone, they have baron, and you are a support. https://static.tumblr.com/413ca52b6e0b29e61b870389693eb9f9/fbfaigb/hTsndlg7s/tumblr_static_tumblr_static_67be512cqj48g0w0c44gwwog_640.jpg

Teamfighting when you're alone and they have baron*

If you jump in 1v5, your team only risks one member of the team, but the enemy team risks all 5 members of their team. Clearly, 1v5 is the absolute best option.

Hey if you're morde then it's already a 2v4.

Where does "Base racing against Baron buff Nasus" fit in this chart?

This image is supposed to scroll a little farther to "Riven tries to 1v5"

Should change baron to elder
