Tom Clancy's The Division's Executive Producer Fredrik Rundqvist spoke with Examiner.com and answered the question of does single player only take away from the experience? He also talked about switching classes mid-gameplay.

It has been ten years of the franchise and a celebration is planned.

It's been almost 10 years since we first stepped foot in Ubisoft's extraction shooter, The Division and it looks like the developer will celebrate by giving fans a chance to replay the experience in "definitive edition" form.

from paulsemel.com: In this exclusive Q&A, the author of the new technothriller based on "Tom Clancy's: The Division" discusses how it ties to the games while also bringing its own story to a close.
Very excited about this one, every time I read something new about it my excitement just doubles.
"Massive on single-player only"<-- Now this just took my attention.
I wasn't thinking correctly and this headline made me sad when I seen "Massive on single-player only" as if, the game is only "massive" when you play single-player and if you played co-op the game was scaled down or something lmao...then of course my brain kicked in :p
GreAt! I been worried we cant play in single player way good!!;)
I wonder if you go solo, will you still be online? That would be my question for the dev. That's pretty important if you ask me. I have a felling that you will be. Which will suck when you come up on teams of people, because it's the internet regardless of what game your playing so your going to get killed for your stuff. In this kind of game where survival is key, your screwed on your own. I've done well on games like DayZ by myself. But if a group finds you, your going to die. There are no "friendly groups" in post apocalyptic survival games.
