Well this makes me feel better. I am a huge spender in game for achievements/mounts/anything to make my main a better player. Hit gold cap 4 months or so ago. Went up to 300k before dropping down to 120k in the first week of Cata (Realm First Blacksmithing and stocking up on cheap wrath mats will do that to you) - Now back up to 200k.
Making money is easy enough once you have an idea of how markets work. If I did not spend on the hundreds of mounts and pets my main has plus a bunch of boe epics over the years I would easily be at 500k+. But in the first weeks of Cata I tried to remember that I play this game to raid and get achievements and that Gold Making is something that needs to support it not take over it.
My big spending is done for now (least till I find someone with the vial drake) and I am shooting for 500k liquid next.
