Weekly I run;
MC for the thunderfury bindings (Don't know what I'm gonna do with the once I get them though).
ZG for the tiger and raptor mount
Karazhan for Attumen's mount
If I feel like it, I run ZG again 3 days later.

Some people might consider this a waste of time but:
From MC I sell Lava cores (30g), fiery cores (30g), core of earth (9g), heart of fire (4g). BoE Tier1 (~55g). The Nexus crystals are converted into small prismatic shard and then LPS.
From ZG I use the coins and buijo's to get to exalted. (The repair vendor outside Gundrak is Zandalar tribe, so exalted = cheaper repairs.) Later on, i'll sell them.
From Karazhan I get lots of stuff to DE which I use to enchant Mongoose on scrolls and sell those for 350-400g a piece.

Other than that, I pick up all trash, skin what I can and DE all greens, blues and soulbound epics. It's not as much as I'd make doing dailies but it's a hell of a lot more fun.
