It's the same in classic arena, the points depend on the ratings. 

Opponents from the top of the list have lower rating than you, winning gives you just a few points, while losing will result in a heavy minus. The opponents on the bottom of your list have a higher rating than you, it's the other way round here.

Thanks never noticed that before, never bothered about points before but I need to get into S4

Dang, I never noticed that either. Guess I'll keep an eye out.

I have noticed it just ignored it as more of their RANDOM BS that they seem to love 😂

i believe the opponents you get in tag arena are just randomly scattered rather than being arranged by rank like they are in classic. beyond that, it's largely the same, save that in tag you can't get more than 13 or fewer than 7 points for a win regardless of the gap between your score and your opponents. classic arena has no score cap as far as i can tell.

The opponents in Tag are random, but only from those close to your current points rating.  So if you are at 1300 pts, you won't get anyone more than about 100 below you. And it appears the majority I get are slightly higher.  You know you are safely going to move up when you see the person with the high score every other refresh. 

Lower ranked teams, at the beginning of the slate, are "easier" to beat and give you less points. Higher ranked teams are "harder" to beat and give you more points.

Such is the logic in the point rewards, if such a thing was true. Unfortunately, because people can manipulate thier ranking based on the defensive they choose and by spending some more tokens pushing, I often find the much easier to counter speed/nuke teams higher. Earlier accounts just pushing up. :)

depends a bit on where you are in your tier. at 1300, they tend to be pretty tight around you. on the other end of the spectrum, things are a bit looser. i'm fairly deep in the red atm and there's a 500 point gap between the highest and lowest opponents on my page.
