I usually picked based on team composition. I look at what the team needs and what we lack in our set up. The main categories I take into account are AoE, Tanks, Poke, Wave Clear and Crowd Control, focusing on a healthy balance between the two. Since you generally want a bit of everything with a specialization in either Splitting, Team Fighting, or Guerrilla Tactics (small group fights in 2/3 sized groups)

My champion pool is big enough to be able to fill in gaps where I see them. But then again I play ranked exclusively, and usually play supportive roles like Support in general and Jungle tanks.
