Hey, tried to find something like this but couldn't find anything but sry if it's a repost.
Well, players who fish alot maybe know this already but for those who don't, you can learn a new "ability" called "Find Fish", just go to Zangarmarsch and fish in the "steampump" pools and you have a chance getting a book learning you this ability.
This shows every pool in the water on your minimap, like "Find Materials" or "Find Herbs".
So when you got this ability, fly around in Zangarmarsch and try find more "Steampump" pools, because you have a pretty good chance getting an item that begins a quest, when you deliver it you will get 10g, it's repeatable so you can get as many as you like. You will also get alot of "Steam Pump Debris", you can sell them for 50s EACH, so after a while you'll get a good amount of gold.
Btw, you also have a chance to get a "Vendor" fish, you can sell that to a vendor for 6g EACH
the quest part can only be done by alliance as far as I know.
Hope this was a little help for all the fishermen out there.
