That and they don't quite get the idea of people changing over time. No one stays the same, no matter how they seem on the outside. I love this new Lel, though I try to unharden her some, I don't want Divine Blood-running-in-the-Chantry, thanks 
Agreed! I have heard folks say they don't like Alistair in DAI cause he is not the same, cause he is not light hearted enough and I am like "But...he is undergoing the calling!!! The whole time he is talking to you, he has gross, nasty little darkspawn music thrumming in his head!!!! AND, think how disillusioned he is with the organization that he was always proud to be part of! AND (if romanced), his woman is off maker knows where!!! And he is hiding in a stinky cave, hunted by his brothers. AND, he is in his 30's!! I am not the same firefly I was at 20! No one is!!!"
Breathe in...breath out...
OK, this was a bit of a rant, but I personally loved both Leliana and Alistair in the new game. I was so glad they seemed a bit older and harder and more realistic. Alistair is still funny, but it is more sarcastic. But he still hides his troubles behind humor, a deeply imbedded personality trait. Leliana is still a smart rogue, but she is having a hard-core crisis of faith when we meet her again. I was SOOOO glad they gave these characters depth! I liked them a bit dark!
Course to be fair...I always write them a bit dark, so I may be biased...
