What's one damage?
You seem to have misread the rules on the honor points. You play 90 for a 3 player game and 120 for a 4 player game. That way it is always 30 points per player.
Quoting from the rule book of the basic game (p. 11)
"Two players = 60 Honor
Three players = 75 Honor
Four players = 90 Honor"
Maybe they changed that in one of the other sets though. I did not check that.
