Never played seriously after WOTLK, but did flip stuff on the AH for a constant money influx, started playing seriously again towards the end of Panda.
Famous last words : "Oh Pet battles sound fun, lets give that a try"
~6 months later, i break the 3000 barrier here on the site, feels more of an accomplishment than the 600 pets.
But boy did I blow through gold during this trip.
I had max gold on 2 characters, now I am broke but have a Zoo. I feel happier now

Anyway, just felt like sharing.
