Tea and I are still in the midst of exploring the other romance options in the game. We can safely say that most other romances are far more fun and interesting (with exception to Ser Blackwall I hear). That Solas’ romance ends in such a way (I won’t spoil why) may not be helped, there simply wasn’t a lot that happened during the romance and only the vaguest sense of Solas’ character and motivation is revealed. Nothing done by the player will change the outcome or his treatment of the player. While little happens with Solas, Iron Bull’s romance contains excitement, hilarity and clearly a lot of thought was put into the writing of the relationship. With Solas it’s all really just…devoid of substance.
Maybe this will all be cleared up in whatever follow up to the story Bioware has planned.
