I’m level 38 with still only 60g despite selling loads on the AH and not buying more than half my skills so I really need to optimise my income for the next two levels.
Am I likely to get more gold from questing or grinding SM arm/cath? The silver drops from cath are nice but I can’t say I get much good vendor trash and I’m sharing the greens with 4 other players.
Questing can be a bit unpredictable when it comes to income though.
You are on the curve or above it. Every level you gain will ramp your gold income. On early 40-levels you will start getting greens and grey weapons vendoring for above 1g. Plus more from rewards and more from mobs.
Questing, even getting mount at 41 or 42 but just questing. If you want optimal income farm good vendorable things like basilisks on shimmering flats, next to path to Gadgetzan. They can drop up to 10-11s of greys per mob plus bonus of skinning and they can also drop greens, and if it’s a weapon - big bonus. You farm until bags are full and go to Gadgetzan to vendor.
I had like 68g when I hit 40 but I had bank alt full of bars and some leather. By the time I got 40 some AH market actually developed and managed to sell all of my bronze and tin plus a bit of leather. By the end of the day and one shimmering flats run I had the mount.
