Region Buffs Idea
So... just a thought...
What if we were to give champions small aura buffs based off their lore; their home region?
For example...

Each of these champion claim the Frejlord as their home. What if we were to create some team buffs because of their connection to the frejlord?
Like "Ashe" would give a buff called "Focus" - All champions from the Frejlord gain +5 attack damage/ability power when Ashe is on the battlefield "Sejuani" - "Bravery" - All champs F.T.F. gain +5% movement speed when moving towards enemy champions "Braum" - "Solid Ground" - All champs f.t.f. gain +5% bonus armor/mr "Lissandra" - "Ice Born" - Taking damage from Lissandra causes enemy champions to be marked with a debuff that allows all other frejlord champions (allied) to deal 5% additional damage while marked. Mark lasts for 7 seconds and enemies cannot be remarked for 12 secs.
My thought was that something like this would encourage more lore-based team builds. This idea could be taken for Ionia, Shadow-isles, Noxus, the Void... so on and so forth.
