Guild Wars 2

I think the main issue here is that the chest drops 2 guaranteed Exotics (aside from the 20slot and the access).

If you look how the loot table works then you would understand that this event holds the highest chance because of the reason above.

as long as anything has a chance to drop exotic then you have the chance of getting precursor.

Having 8 lvl 80s in this account, yes i can confirm that this works.

@king completing all 3 paths on 1 character resets the DR.
assuming you have 3 characters and lets name them a b c.
If you ran it this way; 1a 1b 1c 2a 2b 2c 3a 3b 3c then DR will kick in. But if you do it this way 1a 2a 3a 1b 2b 3b 1c 2c 3c then you will get 60 tokens per character per run.

@Robert
except the dailies dungeon +40 tokens are not account bound.
if you ran path 1 in 2 different characters DR kicks in. if you ran path 1 2 3 in one character and 123 on another you will get 180tokens each time
