I know you can only do so much, but the remnant system needs some SERIOUS work.
I've already complained on how INSANE it is, on beginner, where you find a faction and the jump over to the SK. It's literally INSANE.
But, I've also noticed things you REALLY should fix. For instance, I went to war with (because of the INSANE SK conversion) the dwarves. Well, I gave them the beat down and wiped them out... ALL OF THEM. Now, I come across the Yeti - you know, the Yeti who hate the dwarves.
Now, instead of them saying: "You precious furless humans are wonderful for wiping out our sworn enemies the dwarfs" and getting +4 to their faction, I instead get "You are talking with our enemies the dwarves, How can we trust you"
Seriously, if you've wiped out an enemy remnant, you should get a huge boost. Or at least, not the lame "I see you're talking with..."
