Me do da mining ting, but me dont sell usually, cuz me do engineering, and also help me wife out wid blacksmithin, so me dint have much money when me hit 39, best cash me could do den wuz grinding.
Me went to gadgetzan and went north through mountains, right as you exit mountain path to yer right is a lil pond with aligators, kill dem fer great grinding exp, and approx 4 gold per hour plus some green and potentially blue drops.
but fer makin da lil extra me needed at da end to git me mount, me put a stack of iron bars on AH split up to sell dem 1 at a time for 20 silver each 20 bid 20 buyout, dey sold purdy quick.
Engineers basically lose lots of money, lots and lots, but makes me a warrior much more powerful, and fun. But there is a couple ways to make some cash:
First one you run across is mechanical squirrel, you can usually buy dat schematic from AH, then sell da squirrels you make to AH, some people want one for some reason.
Second is EZ-throw dynomite, never tried selling these but dey would prolly sell ok.
Third is Advanced target dummy, make a stack and go to desolace, sell dem dere, people need dem for a quest me tinks, cuz dey always shouting any engineers that can make me Advanced target dummy please please please???
Fourth one me find is prolly da best, and me do it every time me go through Ironforge. Go buy engineer's ink and blank parchment and make a Goblin rocket fuel recipee, cost approx 25 silver to make, but you can easily sell it for about 2 gold, me usually see what others are currently selling it for and put my bid and buyout just under theirs. Me also /2 Any alch's wanna buy [Goblin Rocket Fuel Recipee] for 1 gold before I put it on AH for 2 gold buyout? Me got couple responces sometimes, and just make as many as people respond, den meet up wid dem and sell each, and put one on AH. Got hassled in /2 once buy some smartypants who said 1 gold you crazy, only costs about 2 copper materials to make, me said it just like any other craft, you pay for me to know how to make it, not for materials.
Other potentials are fishing lures, guns, ammo, and scopes. too much competition here cuz peeps level up on ammo, and guns and scopes havent sold good for me even though peeps need them. If you can get sniper scope cheap (not likely) you can make cash selling them.
Sorry fer me poor comunication skills
Being a high end engineer has prolly cost me about 200 gold, but it is worth it when I can throw a bomb that does sick damage and stuns for 3 seconds aoe after gathering up 6 mobs for my group, or when things get worse, I can also throw down a target dummy to taunt extra mobs, and when we are in real trouble, pull out the dragon, and then use jumpercables on the healur. I think anybody who wants to be a serious tank, should be an engineer, leave the flower picking to the druids, and the skinning to the hunters IMO.
Sorry was lengthy.
