If you dont know what to do with your conqust - you can dump it to buy the rnd equipment boxes and dont open them until after the season. If opened after season end they will contain some gold, 200 i think.
This macro will auto click the popup which asks you if you rly want to buy the box.

Bind this macro to a key and smash it while right clicking the conqeust boxes to dump all conquest in seconds.
The alternative is using an addon called BuyEmAll which buys all the boxes at once for you with a single click (by doing Shift + right click with the mouse on the item when you opened the vendor page)
I usually just get the addon, buy all the conquest, then remove the addon until the next season I need to do this
Nice I have over 25k conquest each on 8 characters, could have more but I havent played so much this season. Some have just 1 character for all season with barely 20 games, I understand they wont gain much from this.
