Ability to pick teams for different regions?

think this would be good like pick a team for na, another one for eu, another one for latam etc.

Nah, that's gonna be a shit tons of flairs and
flair check replies.

Could copy that 1 CS website where you can select as many teams as you want to be a "fan" of and then from those you pick one as your display/flair. The ones that aren't the flair would just be shown in your profile.
