Whilst on the subject of the final battle, I wonder how our advisors will play a part in that?
I mean, will they be on the battlefield as npcs fighting along side us? Or will it be a little like Mass Effect in that they'll be there with their respective troops/assassins/contacts prepping them (like Wrex with his men) but we don't ever actually see them in battle and instead (like DA:O) their troops/agents/contacts can be called into battle to help? Or maybe it'll be a little mixture of everything and throughout the final battle as we fight our way through to get to the big bad/veil tear we encounter each of them one by one in the field with their respective groups, along with any companions we didn't take into battle with us with their respective groups/together? Or maybe we'll just see cutscenes of them fighting and ordering their individual groups around as we push our way through each "segment" of the battle?
I would love love if they took all the gameplay design aspects of all the final battles of their games and put them all together.
So we get a little bit of Mass Effect, like you said, before the big battle. We see our little core team of leaders addressing their own teams-- Vivienne and what's left of her Circle, perhaps Iron Bull and his mercenaries, Cassandra and her Seekers, ect... but we also get a little bit of DA:O and ME2's Suicide Mission, all rolled into one glorious cluster of awesome. Before the battle, we talk tactics-- "Iron Bull, Sera, and Dorian, you're with me."
And then the Iron Bull says that his second will be leading his men, where would we like them? He recommends that they be placed at the vanguard, leading the charge. Hit 'em hard before they can do anything, he says. And let's say, I dunno, Blackwall disagrees-- he says that his Grey Warden contingent would be better suited for the vanguard, and instead, the mercenaries should be placed in reserve. And so on.
But at the same time, there's also 9 companions, which leaves 5 left (assuming you take a full party), plus your advisors (although I doubt Josephine will be in the middle of the fray). So perhaps we decide who leads the other team, and as we battle on, we get to see them-- and that's where the DA:O final battle bit comes into play. You get a messenger from Leliana that something big is coming up ahead of you, but she can get bards to set up traps that'll slow 'em down--or, she can send them to aid the mages and templars, who are getting overrun. As we fight, we see templars defending mages! Mages healing and defending templars! Cut scenes! Show me the atrocities of war; show me how they try to beat us down and brutalize and murder us, but show me how we're fighting! Show me the difference that we're making! Show me the fruits of my labour through all the hard hours I put into this game as my Inquisitor! Show me how my decisions have changed and affected things.
God, if they could just. Just. All of that. More than I can articulate.
EDIT: Whoa, sorry. I got so carried away I didn't even answer the question. Uh. Sorry.
I think it'd be cool if we saw Cullen rallying our troops, or Leliana speaking quietly to a group of inconspiciously dressed people who are also very well armed and clever. Seeing as apparently when we send them out to do missions, they become unavailable, I will be extremely surprised if they don't lead or do anything during that final battle. Especially Cullen, seeing as he's in charge of our military and all.
The only thing is I can't think of what Josephine would be doing during the final battle, seeing as she's a non-combatant (as far as we know, anyway). I highly doubt she'd want to just wait idly by.
