It's not exactly a cut and paste, you're being ridiculous. I'll say it again, how it's executed is very important. But ok let's say God descends from heaven and writes in stone that what I wanted for a finale is a total cut and paste of the last two games.
Ok...*shrugs* so what? It's a proven formula that works. You'd basically be combining the most well received parts of finales in past Bioware games. The tactical decision making and prep work from the Suicide Mission, the grand epic battle type of sequence from Battle of Denerim, and the touching moments with your companions from ME3 and DA2. How is this a bad thing?
Not saying it's a 'bad' thing per se to want it. Just saying I found it refreshing they went with a different formula this time, especially considering the long load times.
And you get 'final convos' with your companions, it's just done prior to going to the war-room to trigger the final fight, and instead of them all lined up like a Starbucks service line, you go to where they hang out in the keep and chat with them. Those conversations felt far more organic and natural to me than stopping what I'm doing to chat them up in the middle of a huge battle. Just because it was done that way in their other games, they shouldn't just stick with it 'because it works'. Following that line of reasoning, if people had only stuck with stone tools because 'they work'--and those knives were sharper than scalpels--we never would have advanced out of the stone age.
Could they have done more implementing Corypheus in the overall story? I think so, a lot of it I felt was like other posters have stated, that it seemed after Haven, there was sort of a let down in the story, though I loved the overall game itself and Skyhold. But the final fight, I was okay with how it played out. I didn't need more.
I'm sorry if you (and others) did.
