My personal belief, is because of the bandwagoning. I've seen it in most multiplayer games that allow players to choose factions. A player initially chooses a faction based on colors, lore, etc. They play, then realize that for one reason or another, one of the other factions wins alot more often. So that new player goes through the growing pains in their initial faction (contributing to that faction seeming to be so bad as well), but then jumps to the winningest faction with their experience, as little as it may be. So now, the "bad" faction has lost another player who could have potentially become better, and actually helped improve their overall performance. From asking people who have BR 100's on all three factions, they do say that VS has a bit more newb-friendly starter weapons. What that translates to is, if something is newb-friendly, it is WAY easier for an experienced player, say one who has gone to BR 100 on one or two previous characters. An experienced player will be able to take full advantage of that newb-friendly weapon, making it a monster. I believe their are plenty of people who started off on VS, and stuck with it from the beginning, coming into their experience. However, I believe there are WAY more that jumped to VS for the aforementioned reasons. Even when watching BRAND NEW players stream the PS4 beta, I heard them say "My friends say VS is easier and they seem to win all the time, so I'm thinking of just going to VS instead", of which I try to stop them by telling them the challenge of being the underdog is more fun. Those were players who have only been playing the game for a few days/weeks. Don't me wrong though, there are players that can make everyone look like newbs on all three factions, because they are just flat out good (or cheating, who knows nowadays).
