When are the old series/feast rewards returning to the game?

[Araxes]

We have seen the early rewards returned. Bronze through Diamond Lonewolf accessories were season 1 and 2 rewards plus minions Hellpup and Faepup were season 3 rewards!

Those were Tier Rewards, not RANK rewards.

You got them when you reached Bronze, Silver, Gold and so on. The Ranked rewards are a different story entirely.
