Ok if you have a brell's fishing pole you are set. Summon your rod and place in primary. Buy your catch-o-lot bait and you are set. The brell's pole is unbreakable now. This is as simple a macro as you get for fishing that works.
@ChatWithThisName 's fishing macro is definitely the one to use. I dont have a fishermans companion so I bought a stack of catchalot bait, and like 10 poles, and let it fish all night. By the next day it was at 200, and I didnt have any stupid boots, daggers, or other junk. incredible work!!
