Introduction/Notes
Okay, I know you probably will underestimate and prejudge the guide before you read, due to my 'leecher' status. But we all have to start somewhere, right?
At the moment, I've only done this with Alliance, but I'm sure you can find a similar spot,I can do horde later. At any rate, onto the guide.
Downloads and Required things
Well, there really only is one download, the recent version of MrFishIt by nesox
Notes
You may want LootFilter, you will get ALOT of junk. You also may get a stack or two of Firefin Snapper, and Oily Blackmouth. (Gold??)
1-50
First go to the fishing trainer somewhere in Stormwind, or Ironforge. Either one. Find a discreet pond or water source there and get your fishing up around 50.(Hide window and alt tab maybe? ) I'll post screenshots of some spots later.
50-150(+)
(Alternate to the following: Fishing deviates in WC)
Okay. After you get that, fly to Menthil Harbor (Wetlands) and go to the spot marked on the map below.
I recommend being at least level 60, that way you don't pull the random murlocs and things around there.
I fished there until at LEAST 150 fishing. ( Took 30mins-1hr ((Again, Alt-Tabbed)) )
I've stopped here because I'm still experimenting spots in STV, right now I'm using the lower docks of Booty Bay, but I watch the screen often.
