Ranked map pool packs?

Kinda wish these were available by default, is this something that can happen, failing that how to find?

Ranked maps are made available to play in custom games only when they're not used in the current season. Maps from the previous seasons are available at the bottom of the "PA" tab in the system browser.

Thanks G, a shame, would be nice to practice some of them during the season though.

Older ones often get rolled back in so there's a benefit to playing on what's available now.
