They say it both in the video, and in the rules under Tournament in Records on your profile.
NOWHERE DOES IT SAY LOSING A MATCH = NO POINTS
They bring it up in the video
i dont see it in the patch notes tho. obviously a miscommunication at naughty dog.
Well now you know, and they made a video explaining the Tournament system for a reason
Yes!!! This is a really bad part of this good system. They should at least give you 50% of the points you would have got if you won ,if in any way you lose. This would be a perfect way to get points and not waste tickets!!! Please do this Naughty Dog!
