OK initially I thought this was a handicapping system for scenarios where one side has a harder time that the other side. But it looks like (from reading some forum posts) that it's more like bait to get people to play the games? Is that right?
Sorry, I'm not sure exactly what you mean, as both sides always need 100 VPs. Do you have any specific examples?
If you mean the VPs scored for (e.g.) killing enemy units, it's because every so often I look at the game stats to see if any missions are unbalanced. If they are, I tweak the settings to try and make the mission fairer.
Ah no I meant the league VPs awarded for winning each game, not the VPs that are the victory conditions inside a single game, which as you say are always 100.
It is a kind of a handicap system, it all depends what league points you have, the higher the points you have the less points you get for a win, lower you are, the more you get, plus less points for a loss.
