This may seem like common sense, but with the release of Nesox' new MrFishIt for 3.1, we have come to know the days of memory scanning fish botting and not color recognition, meaning we can fish in locations which are otherwise bobber-fests.
I used this in the fountain of dalaran, watched some youtube videos, and when I came back I almost had all of the coins.
Once nesox fixes loot tables, we can also use this to farm for our giant sewer rat. We can also use this to farm for out special fishies in IF/Org, any of you alliance know it's a bitch to set up the bot to fish in the dark place of IF!
I don't know if this is common sense to anyone, but I just thought i'd share.
