Been playing since Naxxramas, never really taking a break for more than a month. Kind of scared to know how many hours I've sunk into this, but also interested, alas. Used to play arena for years, then focused on low-rank ladder using only decks with 40 legendaries. Nowadays I play mostly Battlegrounds, with the occassional arena run, 35-legendary wild game, or Whizbang standard match. Since I never tried to compete heavily, I never felt any pressure to pay for anything, and hopefully never will.
