Suggestions/opinion

Thought i played Original mod alot, it never properly expanded as updates come. One of things was limited amount of immortals and then easily you could be last one. Original mod gave you flat atributes. So i think it could be changed.

1) New immortal should use tiered trait system.
2) Treits should give wide variety modifers. Like defence against plots, Army advanatages. Survival on army if there is no enemy immortals as knights. scheme bonuses and so one.
3/ also i think there should be another tiered trait that is directly connected immortal trait, like Focus trait aslong as immortal tier increases you can get adional exp on certain focus trait to get adional bonuses. Does Immoral be create army leader or good and managing estates or silver tongued diplomat.
4) immortal adventures and territorys. Immortal gets notice/feeling that another immortal is diplomacy or territory range. And can chooce to confront or ignore it.
