I play 2 to 4 hours daily and I am getting about 5k per toon from orderhall missions, about 15k per toon from doing WQs, dungeons, etc. and very little maybe 3k-5k per day total on the AH.

It takes some build up though, need max level and many time gated quests to open everything up. If you're looking to pay with tokens your first month back it will be tough without the standstill farming. The neverending elites in Suramar probably a good place.
