Hello.I couldn't find anything about this thing by searching, so here is my experience:
After reading about pushing the Questcounter by turning in a quest again and again I found the following:
My questcounter (for "The seeker") displayed something about: 2457 Quests Completed
after accepting and turning in the "Could I get a Fishing Flier?" - Quest my Counter jumped to: 2948 I asked my guildmates to test it.Same for them.So if you need your "Seeker"-Title it may be an easy way to push it by this quest. For a DK in my guild the counter only did a +50.
