Feeling Nostalgic? Check the Archive

You can now enjoy older Seasons in the Season Archives, maybe you’re new to the adventure, or you want to refresh your memory with the ghosts of Seasons past.

Access the Archive in the “Battles” Tab. Everyone who purchased a Season Pass while a Season was active will have permanent access to that Season in the Archive and any player can get permanent access to the most recent past Season for Crowns while all older Seasons will be available for Gems.

Individual Seasons will also periodically open up for a limited time!

It is now season 5, and there was no further mention of ‘opening up’ old seasons.
Have the plans changed, or we can expect it to happen later? Will it include old goals?
