It is in my opinion that some people prefer survivors because they don't like enemies coming back after they have been killed once. I believe survivors is the easiest mode to play because you don't have to worry about more than four potential enmies within a certain time frame. With the low time limit it is also easy to camp and hide and players tend to make more mistakes when being rushed due to lack of time.
In supply raid you could have up to 24 enemies and interrogation is unlimited. The pace can be very fast or very methodical and you always have to be on your toes in those two modes because you don't always have the advantage because you got a lucky kill or 2. Survivors is the opposite. All it takes is one lucky headshot, bomb, nailboard, or mollie to swing the match your way.
Supply Raid is a joke. You have multiple lives, weapons can be kept, boxes respawn, it panders to COD style run - and - gun gameplay.
Oh I died? That's fine, I get a million other chances anyway, and I keep all my stuff!!!
Don't get me started on the spawn points.
It's by far the easiest, most casual game mode. It is made for beginners and/or with no skill.
All the complaints I have read here so far about survivors can basically be boiled down to "I died this way and it was annoying"
Sorry, don't die next time, it's kind of the point.
^"Survivors is easier", not really, kinda subjective, it's just slower paced. SR and Int. are fast paced and players know they can respawn to a limited number or indefinatley thus giving them more wiggle room to be more of a risk taker. I have used myself as a target to draw out snipers and allow other teamates to sneak up and shiv them. If I tried this in SR, it wouldn't be as useful since stealth is not a big part of that game and other team members would be more focused on other things from my experience and I knew I could respawn anyways.
