The thing is, this game is about PvP. (Mainly, not all.)

People will be in the abyss trying to kill eachother, if say, 1 rich guild can afford to give all it's members SS, then that entire guild will basically be pwning harder than anyone else. Other people get mad, they buy SS, now their is more people with a small advantage, even more people are getting owned now, so they start getting SS. Eventually, everyone is gonna end up buying SS to keep up with the rest of the competition.
