Believe it or not, I got this idea from RuneScape.
Here is my idea,
1. There should be a master quest list, all the quests that you have completed are highlighted as green, all active quests are highlighted as yellow, and the quests that you have not started are highlighted as red.
2. Each quest gives a certain number of quest points depending on the difficulty.
3. The helper title becomes available once a certain number of quest points are reached.
Well this is what I have came up so far.
NEW TITLE: Canthan/Tyrian Helper

basically the same with the mission titles where it states xx/25 missions complete in tyria. but just different style of colors and listing. no need for it. only if you can buy stuff with the points, like collectors do, but with different things. i still think though its not needed.
