Fishing After ARR (Please, help!)

Hi!

For the first time in my life finaly I got lv 51 on my fisher job (yay)!
But, after reaching Foundation and doing the lv50 quest there... where we go? I found only one lv51 spot at Falcon's Nest for skyfishing (and get 2 types of "fish") and nothing more of my own lv. Others spot on the same map give me only 1 kind of fish forever with the same low xp.

How do you guys do when reaching the same bottleneck? Do I have to go back to ARR until get lv54 in order to fish on the "new" areas? This will happen on every lv from now until the lv cap?

Why such an awful developement of progression on this job? Why not more lv50 fishes and more spots of this lv to catch them? '-'

The progression on ARR was awesome! With that final fish to catch with double mooch. That was awesome! But then, after that only few places to go to grab a worm and 2 new fishes forever... '-'

How to solve this?

Follow the collectibles. The skyfishing spot should give you glacier cores.

You can buy level 51 bait at Falcon's Nest, Stonefly Nymphs. If you're only catching low level fish it is because you are not using the higher level Heavensward bait.
