It's a widely accepted idea that there is a 'pity timer' when opening card packs in Hearthstone, meaning that after X number of packs opened without a Legendary card, your next pack will always contain (at least) 1.
After a recent 12 wins run (Yay!) My reward contained 1 pack, a bunch of gold and a Legendary card. At that point I thought maybe I hit my pity timer, as it had been a lot of opened packs since my last Legendary.
Does a Legendary Card obtained as an arena reward resets the 'Pity Timer'?
