I don't exactly save my Hearthstone gold but I end up with 5000 saved because I really only buy packs when there is a card I REALLY need, and the ammount of viable cards in Hearthstone is really not that big.
To my luck, I was graced by the tri-faction pack bug and end up with some nice extra packs.
Now I have Hearthstone to play, Dota Boston Major to watch and I haven't finished Rabi-Ribi and touched the new season of Overwatch.
I'll probably skip some of those for my sanity.
