On my server(which is Sentinel)I'm trying to find a engineer to make some stuff for me for that quest in the Eastern Plaguelands and I ask everywhere on the Trade channel,I ask for days and days and I found no one,I even ask in BG(don't judge me)no one is.So I'm asking,where are all the engineer and what kind of class are they good for and how can I find them?

All classes are good for engineering. You probably just have a shortage of engineers because
A:) Rotten Luck
B:) Everyone on your server decided engineering didn't make any money and it didn't have any use other than for fun and some shortcuts, and that it wasn't worth spending the blood, sweat, and tears to level it.

90% of the time, it's B.

you on a new sever?

its not that hard to get your skill up. All you need is to be a high level and have enough money for mats at the auction house. It may be that im on an overpopulated server (Llane) but i got my skill up to 189 in an hour, its not hard...just keep buying ores from the AH, don't bother with mining.

really?  on my server they're everywhere.  (altar of storms)  seems like every other gnome is an engineer on my server so maybe try specifically targetting them.  go to ironforge and check there maybe.  hang out by the engineering trainer on weekends when its busier. see who comes by.

well im an engineer on bloodhoof and i have made alot of engineer friends here in dwarven district is where you will find most engineers.

i have made mates around dwarven district at stormwind and they help me with supplies if i run out or need to buy some more

Everyone thinks that engineers have to spend a ton of cash on all their stuff but they really don't, all you need to do is get them from alt characters with professions that can get them for you.

really?  I'm on Sentinels, and I'm an engineer. ;)
Fun stuffs!

y not add an incentive when ur looking for an engineer.
i see post look for engineer but i dont bother cos im lazy. usually its for something cheap like a tube or a scope and isnt worth giving tips on.
