Forum:Liara Canon Romance

Recently while going through my yearly playthrough of the trilogy (as usual I stick to my favourite of Talimancer or Shakarian in terms of romance) I couldn't help but notice the finer details of Liara's character and the fact that she seems to be placed quite prominently by the developers to be the 'canon' romance option, here are a few examples of reasons why this seems to be the case:
 * 1. While I never personally experienced this as I never romanced her it's generally seen that she has the most 'risque' and lengthy romance scenes in the games, plus the largest amount of scenes available.
 * 2. She is the only character you can romance in all 3 games and as both genders in each game as well.
 * 3. There doesn't seem to be a single opportunity to kill her except for the endings where everyone dies in ME3 or the final charge in the Extended Cut, unlike all the others who can die at various points in the trilogy.
 * 4. The game seems to actively try to dissuade you from the Virmire Survivor in ME2 by making them give you the 'Horizon Treatment' in the fact they act like complete tools, while Liara, though cold, is given justification and is given redemption through LotSB DLC. The prickish behaviour from the VS continues in ME3 where half of their dialogue in the games seems to be designed to make you hate them with their constant questioning of your loyalties.
 * 5. She is also the only romance option in ME3 that is available in the first half of the game (bar Garrus) as all the others are locked off or given extremely small amounts of screen time (VS gets hospitalised, Tali is locked out till Rannoch, you barely even see any of those characters first seen in ME2).

Overall I think this may have been done to allow further spin offs to have a constant narrative to tie alongside with but I can't help but think it had a detrimental effect on other romance options as more time was spent trying to diver the attention to Liara.

What do you guys think regarding her possibly being set up as the 'canon' romance option and do you think this had a noticeable effect on the quality of the others?
