I thought of another flub, one that has not been brought up yet and it’s a big one - Red Lyrium.
Let's be honest the whole Red Lyrium explanation was not only a clustered mess, raised questions and contradictions.
I'm going by the choices I made in DA2 and DAI.
At Haven The Herald asks Varric "How did Red Lyrium show up at the Temple?"
Varric responds, "I do not know. As far as I know the only piece brought to the surface was destroyed."
No, it was not the only piece. Yes, Bartrand did kept a small piece of the idol. However Varric spends his free time trying to track down who Bartrand sold the idol too - which was made out of Red Lyrium. Later you find out Meredith was the one who purchased the idol and turned it into a sword.
Varric tells Blackwall that they have not moved Meredith from the Gallows after the Red Lyrium consumed her and turned her into a Red Lyrium statue. This sounds as if The Gallows was completely shut-down and blocked off to contain the Red Lyrium.
However the Templars (including Cullen) continued to operate out of the Gallows for about three years. Considering that Red Lyrium drove Bartrand and Meredith mad and it spreads; the Red Lyrium should have driven The Templars mad and The Gallows should be covered in Red Lyrium.
Varric also says "It took years for the people of Kirkwall to become infected and they were not actually ingesting the stuff."
This sounds as if the Red Lyrium from Meredith was spreading and getting out of control. Thus leading to Kirkwall being over- taken by Red lyrium.
Again we get thrown confusion when we receive letters from Aveline and Seabass at The War Table from Kirkwall.
After "Into the Abyss. " Varric says, "I better let everyone back in Kirkwall know where Hawke is going."
Two problems with this. One, Again Kirkwall should be overrun with Red Lyrium, insane people and people being consumed by Red Lyrium. Two the only person in Kirkwall who Hawke knows is Aveline, so who the hell else is Varric speaking of?
At the end of the game, Varric tells The Inquisitor, "I am heading back to Kirkwall to help with relief efforts."
Relief efforts for what? All the information that was told suggested Kirkwall should be gone - consumed by lyrium and the inhabitants are probably beyond saving. Hawke managed to keep Varric from going crazy by the piece he found in Bartrand's estate now he wants to go back?
The other issues with Red Lyrium are as follows:
Anytime you and your companions are around Red Lyrium nothing happens - especially if you are playing a mage and/or mages are in your group. It's as if you are walking past cherry flavored Jolly Ranchers.
If you judge Samson at Skyhold, he arrives wearing his Red Lyrium armor and Cory is no longer delaying Samson's corruption. So would it not be wise to just have the option to execute Samson? Yes, by all means let's let the walking Red Lyrium crystal guy into Skyhold, that is going to work out so well - especially if you choose Samson's sentence to be in prison for information and Cullen to be his handler.
