I think that raid defense doesn’t add enough points. E defense is 200 points, but A defense is only worth 900 points, a difference of 700 points. That means a good defense team usually only equals one additional win. I would like to see defense score range be equivalent to one day of raids (~2000 points) to balance out the offense and defense aspects of the tournament.
They need to fix defense-matching first. Quite a few folks experience only one or two defensive-battles, and get stuck with that grade (whether E or A). Once they make the match-making system better, it’d be worth adding more points to defense, in my opinion…
