Deciding standalones from group lore?
How do you decide standalone lore from group lore?
For example: Annie's lore ( Though already updated, mentions nothing of other champions or fractions. Only told that she lived far off from Noxus. ) vs. Sylas' lore? ( Noting much of Demacia and champions like Garen, Galio, Jarvan IV and Lux. )
At first I thought it was because someone like Annie couldn't press themselves into certain situations or encounters with other champions, but then Nunu & Willump slaps us with Nunu having a relation with Lissandra and Anivia in some way.
