Guild Wars 2

Me and my team ran 6 fractals in a row.
With the first 3 we got 15 tokens.
Then we got 15 tokens for the second group of three fractals (it’s 5 tokens for fractal).
Finally we reached the seventh fractal, the boss instance.
In chest which spawned after killing him I found no tokens (only green and gold items), and I got no tokens from the chest daily-similar on the right too (I found 2 bags of gold for a total of 4 silvers or so).
My mates instead got 60-85 total tokens (15 in the chest and someone 20+20 even in the daily-like reward). I ended up with 30 total tokens.
What happened? Is it bad luck? Was my reward bugged? A really sad end of the dungeon for me. The fractals were so nice… But I got less than half of the tokens!
