I have recently got my first 120 Fishing ps and having waited for it for too long, I immediately used it and used 5.0 sot to get from 115 to 120 fishing. The following orders I got from the fish mongers were all 1 to 3 liners, yet still all for 20 fish. I saw my first 5 liner after three days and approximately 25 quests but even after that, I frequently got 1 to 3 liner quests and seldom 4 or 5. I already had 115 fishing before using the ps, so it is not related to the "adding dungeon fish to the equation" idea. I just checked the last 20 quests before using the ps, all of which have 4 to 6 lines except one. Any idea why this happens? I hope I won't need to complete another 500 quests to finally see 6 line quests as frequently as before.
