So last night I had a dream. Which gave me an insight in possible new content.

Each beast tribe has a faction. You join said faction and perform campaign missions against other tribes via fates and quest-leves. Granting you points from that faction aka "Sylph leaves" you trade them in for exclusives like vanity sylph armor, mounts and minions. housing and so on.

Note: While I can see that the dailies are something similar, the difference is that there isn't a daily cap of quests. But it's time based on leves and fates.
