We really want to look at Mass Effect 3 as a standalone title
I was afraid of this. It's one thing, from a company/business kind of view, to attract new players. But another thing is to keep your current costumers happy. But screwing around with the word "standalone" while they have clearly stated that Mass Effect is a trilogy, is just wrong.
They already used their 'get outta jail free card' once, using it for the second time makes people really doubt the overall plotline and storytelling abilities of Bioware. They can't just remove the squad again because that would be easier for them and would be better understandable for new players. The reason for this is because of the plot. Every squadmember knows the threat. The council doesn't want to believe it(they have dismissed that claim), the civilians don't know about it, so the only people that do know about it, is your squad.
And like I said before, killing or making Shepard disappear again, would just be a case of bad storytelling and that would really, really break ME3 for current players. Then the whole idea Bioware had, about making this a rpg-trilogy, failed big time.
Why is this post more about your squad? Well, because that's what most people are afraid off. That your squad gets sidelined once again because it would be easier(which wouldn't btw, because then they have to come up with a lot of new characters)
Storywise, I think it's kinda obvious they're doing this. Mainly because the plot isn't so difficult anymore - stop all the reapers. The only real problem they would have, is how it begins. People want to make their own Shepard and change his/her class. ME2 did this the smart way - by killing Shepard off and remaking him/her. But they can't do this the second time(as I explained).
But we'Il see..
