You can probably do ok at 150fishing. Definitely use Night Crawlers. You can buy them in booty bay where the advanced fishing book is sold for about 90copper each. Obviously you can get plenty in Duskwood killing Plague speaders or similar foe.

Get very good at panning your camera view behind you while fishing. The horde are cowards any love to attack when you're most vulnerable. Be able to switch back to your weapons FAST. I've had horde try to attack me.

if you're not on a pvp realm and not flagged for pvp, you don't need to worry about cowardly members of opposite factions, but you should be prepared for mobs if you're in a highly populated area.

a peaceful place that i've found is just south of booty bay, off the docks,  also up in the northwest corner of the zone where it meets westfall.  no mobs, no players, although near booty bay, you will occasionally get some players.

fishing is supposed to be relaxing.  try to find places that are just that.  >:}

Pretty nice comment considering I have never been attacked from the front by an alliance whether fishing or questing.

That's funny, because my 40 blood elf was absolutely destroyed last night by a fully geared 70 while fishing. Was really frustrating.

I just started fishing in STV, it's pretty fun!
