The chance and luck

[Astrocat]

I was wondering if it was a bug, or not. But after writing down every single chests (silver, gold, copper) and bundles (from Platinum store) that I opened, I did not receive a single pink. Here's what I opened at the moment.

Looted chests:

- Silver chest: Opened 52 times, not a single pink.
- Copper chest: Opened 36 times, not a single pink.
- Gold chest: Opened 16 times, not a single pink.

Platinum/gold purchasable chests/bundles from store:

- Founder's mystery chest: Opened 75 times, not a single pink.
- Founder's weapon chest: Opened 28 times, not a single pink.


Total of chests/bundles opened: 206.
All of them were opened on my account, but on 2 different characters (to test the rate).

Items received: Greens, and rarely purples.

I'm not complaining, or telling anything bad (makes me feel bad), i'm just wondering if it's a bug, or if the chance/luck of this game is really low and depends on the characters.

-Edited, I opened even more now. Again, not a single pink BUT received a common. This is making me really upset!
-Edited again, opened few more. STILL not a single pink!
-Edited, 30 more. STILL NO PINK.
-Much more added. No pink as usual.

Thanks!
