Freljord Only Region Covering All Positions Without Flex or Off-Meta Picks

EDIT: I WAS WRONG! The Shadow Isles, Demacia, Ionia, and Zaun can do it.

The Freljord is the only region with dedicated champs for every position on the team.

Top: Tryndamere, Ornn Jungle: Sejuani Mid: Anivia Bottom: Ashe Support: Braum

The other Freljordian champions are or were viable in two or more roles, like Olaf Top or Jungle.

While other factions, like Ionia or Bandle City, might have enough flex picks to form a full team, no other faction can fill each position with a champion dedicated to that position and not viable elsewhere.
