AD support vs. AP support
At what times should I use an AP support vs. an AD support. I know if the team is low on AP, then I should run an AP support.
I know team comps are a factor as well, but I dont know what should go with what.
For instance a protect the carry comp gets what kind of support. I would guess AP as most have a shield and heal, but Thresh works as well.
If someone could explain this to me, that would be great. I dont ever really hear pros or even people talk about this.
