Tiering the Pathfinder Classes - Summoner

[Thunder999]

Shaman isn't really a pet class, they get a familiar, not a companion you expect to fight things.
Shaman is closest to the Witch, and it's very close, both have hexes, a familiar, and a mediocre spell list while being full 9th level casters.

I'd say Summoner is T2, Unchained version is T3.
