The problem of Rainbow Six: Siege is that it probably will become less and less casual / fun to play, due to the changes announced these days (Dead bodies will now disappear from the map in a matter of seconds).

The after-death gameplay function of the game has been already removed from the game after receiving many negative feedbacks from players and content creators, while still in the testing period;

Basically the same thing is happening with the disappearing bodies function, people are already complaining a lot about it, and we feel like it should be removed too.

Removing this function could make a big part of the fans stick to the game and it could also keep enjoyable the game itself.

Signing and sharing this petition can give this a shot, maybe Ubisoft will consider that the game doesn't just need framerate improvement and competitive stuff to be fun to play.

The optional version of this change should be like this: Players that don't want bodies to disappear can toggle the  disappearing function off.
