Is sludge mining good?

[duality_gaming]

Ive been grinding f6 for cata exp and the rng meter giants sword but ive realised ill have to go through 400 runs and the money wont be very good considering itll take me like 20 hrs to do that many runs. Tho ill be cata 32 by then so pretty good ig but i dont want to keep doing f6, and i also want consistent money, so is sludge mining a good mmm?
