Leliana's in a DLC!
Balancing character reputation is kinda rough in this game, for example Anders likes when you support mage freedom, Merrill likes if you're okay with blood magic and demons, Fenris likes if you like the templars, Isabela likes if you're a sarcastic flirt. Varric and Aveline tend to support Doing the Right Thing (TM).
You can still romance people even if you're in a rivalry with someone instead of a friendship, it does sort of change the romance though.
because (SPOILER)the mages are right, smurf the chantry and the templars![]()
