hi!
I'm at 109 fishing and haven't turned down or cancelled any quests. suddenly, I'm receiving quests for 1 line shore fish (10 count).
is this normal?
Yes - something that occurs about the time you start getting dungeon fish quests messes up the entire calculation method.
The calculations are supposed to be
chance for 2nd line = (number of fish types you've completed at least (one) quest for) / (total number of quest fish types), presumably times some other variable to make it not 100% every time (we'll call this "C").
The chance for a 3rd, 4th, 5th or 6th line works the same way, with (one) above replaced by the current number of lines in the calculation. When a chance fails, that's where the calculation stops, and you get the quest.
Now, when you start getting dungeon quests, that should make the divisor (or denominator, if you prefer) increase by 12, instantly causing the chance of a 2 line quests to drop from 100%*C to 77.77%*C (and a 72% drop in the chance for a 6-liner, as if you'd done 5+quests for all the base 42, that's a change from 100%, to 77% to the 5th power), but you slowly get that back as you do quest lines for dungeon fish.
That's in
THEORY.
In reality, the drop seems more severe, and the recovery doesn't seem to come.
The numbers are messed up, somehow. Our best guess is that they accidentally added some or all of the trophy and recipe fish into the divisor along with the dungeon fish, or that the change in the equation to take the dungeon fish into account is broken in some other way.
I'm at 117, and I'm still getting 1-liners occasionally, despite having done 5+ quests for all fish types that fit quests.
So yes, it's normal (currently), but I don't think it was intended.
