Because difficulty of acquisition between fisher and botanist and miner is completely out of whack pre-HW. If you need something special for a botanist or miner pre-HW, you just show up during a certain time window and pick the right slot. If you need something special for fishing pre-HW, you not only need the time and the weather but sometimes two or three weather windows to all line up correctly. And that's assuming they even bite. I have my miner and botanist blessed tools done. I'm still struggling with fishing because I can be at the right place, at the right time, with the right weather pattern and there is nothing that guarantees a bite in that window. It's ridiculous.

I say pre-HW because to get the things post-HW for botanist and miner you need a gathering rotation, but for fisher you just fish it up and maybe use one or two skills to help you. So they balance themselves out more.

I know some people are happy with fishing because it's hard and they equate it to hardcore raiding. I would much rather SE brings fishing into parity with the other gathering classes and gives us three viable gathering Jobs that are well-balanced, instead of two that are well-balanced and one that feels tacked on.
