In case you didn't know - Tankrewards.com is an official "sister-site" of WoT.  They run various ingame missions every month.  Then you need to log in on their site and claim your prize.  I had 24 daily missions done - oh, well, needed 25, not sure how I missed one.  But I qualified for 10 missions prize and got a "mistery crate".   Here is what I received.  "Payment" showed up ingame same day.  Yey! :)

And back to the terrible teams, which manage to lose even with 70% chance to win.

I was as high as 50,94% winrate.  Now I'm 20+ games off 51% again.  But I guess it doesn't really matter since WG changed "borders of the colors".  I'll need 53% to be "green".
