How does the new trait system work?

Question

So the new April feature pack is live and has made some changes to the trait system as well as introducing new traits.

I logged into my lv31 Thief who has 20 trait points to find that all my traits had been reset and I had 1 available trait point.

How have the changes to the trait system led to my losing 15 trait points?

Answer 1

From the wiki,

Each level 80 character now has a total of 14 trait points, each equivalent to 5 trait points prior to the update.
Characters earn 1 trait point every 6 levels starting at level 30, and two trait points every 6 levels starting at level 66.

So it seems that my trait points have been adjusted to match this new system. Because I am lv31 I have only earnt 1 trait point and will need to level up to lv48 before I can get the same number of traits as I had before.

Level    Points earned   Total points
30          1               1  
36          1               2  
42          1               3  
48          1               4  
54          1               5  
60          1               6  
66          2               8  
72          2               10  
78          2               12  
80          2               14
