Varies quite a bit. For months we were consistently into partial to 1 legendary task every week territory and 40k at least once a month. Then things slowed down, which necessitated trimming the roster and rebooting with new requirements. We're now 3 days into our new form and not at full strength yet, so any claims would be pure speculation at best.
You're welcome to try us out; no hard feelings if you move on. We've graduated plenty of members to Intrim, Aes Sedai, Dragon's Peak, MM, etc.
