These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Though arguably it served to further trivialise DA2's plot by having the mage rebellion come as a result of months of tensions post-Kirkwall and the final scene with the First Enchanters. This means that Anders' actions at the end of the game were just one long-term cause out of many rather than being the immediate trigger.
On the other hand, one could argue that Kirkwall reinforced the growing seed of doubt that the Chantry simply wasn't doing it's job properly. The idea that a single desperate Mage could cause an entire city to erupt into chaos was not new, but the realisation that it could take place in a city famous worldwide for the Templars having absolute authority?! Anders' actions may have not been the immediate trigger, but it was the spark that ignited a powder-keg that no-one wanted to admit was there.
Draco in Leather Pants: Some people pine for Cole to end up as a companion or even a love interest in a future Dragon Age game, despite the fact that he's basically a serial killer who never once expresses an interest in sex.
Foe Yay: Rhys and Evangeline are both obviously attracted to each other despite their initial animosity.
Moral Event Horizon: Senior Enchanter Adrian ends up killing Pharamond and framing Rhys (her only friend and the man she claims to love) to spark another battle. She has no excuse for this, beyond the bog standard "mages are oppressed" argument, and it's quite clear that Rhys justifiably hates her by the book's conclusion.
Lord Seeker Lambert arguably crosses this at three different points. Either when he completely disregards his orders to start the battle at the Spire, his brutal beatdown of Cole, or nearly killing Evangeline.
The Scrappy: Adrian. The fan base overwhelmingly wants her dead, and it's easy to see why.
