I don't understand most of your points...
There aren't six people dancing, there on six people on screen dancing. You can hear the rest. You really want an individual shot of every single person there?
People are confused as to why you are being attacked. You seem to be saying that Cullan should not have sent soldiers out when you were under attack? So, he should have waited for them to arrive and kill you?
Why is Josephine looking for a flag confusing? Most armies carry one, and it's hard to counter an army when you don't even know who they are. I would think looking for something that identifies them would be step number one for anyone.
You don't have time to go get some sad farewells from everyone before leaving, and they haven't known you that long at this point even if you did.
It is kinda strange that you companions disappear, but the plan was that you distract Cory, not them. He doesn't care about them, so they can all escape. You do get blown away before the scene, so I guess they all flew off in the opposite direction.
The voice acting is great, dunno why anyone would have a problem with this.
People aren't worried about losing the only person who can close rifts because they are about to die. It might be logical to think about how there is no way to save the world tomorrow, but most people aren't going to care about that when they believe they are going to die today.
So, you are saying me, is logical for you ALL THE PEOPLE IN HEAVEN, is waiting to your awake at the start of the game when you get out of the house, but you just see 6 NPC dancing in heaven?, they can't be dancing in the chantry, and the tavern will explode if all NPCs entered in it
Well, basically yes, you just don't see an army approaching to you and act like you always have been prepared, and then you cry and feel regret because "If we were prepared it could have going so much better"
If someone try to kill you are you more worried about who is than in running for your life?
Ammm, if my character is going to give her/his life for the dirty random people in Heaven I think he/se have the right to do whatever he/she want. (with that logic I hope you always drink from the Well of Sorrows and don't say "My character never is going to give his/her freedom")
I am not sure people like Cassandra would simply let behind "the Herald of Andraste", much less Solas.
I have problem with the voice acting because my character is going to give her life for people that she doesn't know enough as you said, and she don't act sad or angry, in Trespasser you have 4 option to react to the mark, "Oh, ****, damn it" "I don't want to die :c",etc but here you are willingly to sacrifice yourself just like that?
Cullen can be quickly replaced, Leliana too, "The Herald of Andraste" and the only person who can close rifts no.
Is like every NPC in the game, even Corypheous knew you weren't going to die.
