I think i have a better idea for the people who complains because Max is in Kate story :I hope people like this. This update is based on a suggestion I made to DS which was based on several conversations I have had with various people on this thread. If DS implements (ed) it right it could be a step toward solving or at least alleviating some of the complaints people have with max being in Kate's story and give them a way to take revenge on him if they are so inclined.
Don't add Max in Kate story...
I only play Max path, i don't care about Kate (and Max too, i only love villa caracters )but for Kate lovers, Max should be in his path only.
