Well see we are playing the same game but fishing completely different things. Last few times I've level fishing have been for pure speed. Generally speaking no ring below 80 I don't think I've gotten under 1.5 levels a day fishing full 200 to max fatigue in the last 4 times I've leveled fishing that high. I've gotten as high as 5 (10 with a ring one day that had me dancing in circles lol) but usualy average more around 2ish. I generally go to nashmau around mid 50s low 60s. What makes it so great is not only do you get to target 2 fish (Mercanbaligi and Ahtapot) for a good 30+ levels but both have very good bite rates. Like about 25% each. Which means you can fish to full fatigue in 2-4 hours. So yeah my example was on the lower side of what I get but it does happen and nash leveling up is that good. Plus they npc for 600/700 each
