You only lost one point in rating because even the often-ridiculous matchmaking system knows that matchups like this shouldn't be happening. My alliance ran into the same thing this last war. We were at 2380 going into the match, got paired up against 2980, and only lost 2 points because it was an incredibly unfair match-up and the system actually takes that into account when considering points won or lost in the match. The greater the discrepancy in the war rating of the match, the lesser your war rating will change depending on the result.

Thanks for the info It's the first time we've been paired with such a powerful alliance so I had never seen this kind of "compensation".
I think if you looked before the war was over, you probably would see that “IF YOU WON” the change in WR would have been big (for both teams).
