Ok by that logic then?
lets look at it this way;
Fish Count 10 - 15 - 20
# Fish - 1,2,3,4,5,6
so 1 fish 10 count - 2 fish 10 count - 3 fish 10 count - 4 fish 10 count - 5 fish 10 count - 6 fish 10 count ???
Now of course that would mean 6 completely different fish each quest but, if a fish was duplicated then possibly say 3 fish then = 10,15,15
but lets stay simple
next go around then 1/15, 2/15. 3/15, 4/15, 5/15, 6/15 then on to 20's
once you get to 6/20's and have covered it for every type of fish at 20 then you should only get 6 fish 20 count quests.
Which should reason out that once you have had every fish done at 10 count you should NEVER have a 10 count for that fish EVER again. That is progression.
I will have to start keeping track of this but I am almost positive that I have turned in 10 snow crab at the same fish monger more that once.
now one more variable might be that there is a counter for 1 line 10s, then 2 line 10s and so on.
And there are of course 8 mongers so i do see there could be alot of grinding to get there but once I have made it to every fish at 20 count on 6 line quests from every monger then ALL i should get are 6 line 20 count, is that correct?
I will do some math for a # of variable that is and edit it later?
Ok crunched some number 36 simple possibilities on a 6 line quest
8 mongers
56 types of fish
Therefore and this is very simple progression thru the fish and mongers and # lines , ((no other variable))
there is 96,768 quests to be completed until you reach a point were all you should get a 6 line, 20 count quests from each monger.
Have fun, someone else can do the math on how many fish that is.
Again that was very simple straight forward progression through the quests, throw in another possibility of a reset at each count line and well - you will NEVER each the limit in your lifetime.
Now compare this to the rewards and having to get 2 high end lines to get the items for a Charybdis and fishing him up in the 5 bait you get better = somthing WAY more powerful that a 120 fishing scroll or a 120 fishing should pop as loot for EVERY Charybdis at a minimum?
