Yeah, I really hate this. One faction: “Hey, you’re really helping us out. Have a gift.”
Other two factions “WhAt? ThAt MuSt MeAn ThEY hAte US!?” -5 rep.
It’s stupid. It’s just stupid. It’s a low effort, badly made, way of preventing the player from easily being friends with every faction.
You could at least have had things like faction quests where they’re at war with each other and you have to chose a side for certain conflicts. Helping a faction raid another would be fair reason to lose rep with a faction. Not accepting a gift!
Sorry for taking every advantage I can get during literal freaking Armageddon, I guess.
