There's two common problems I've noticed that others have brought up. 1) it's not about how overpowered it can be, but the fact that there can be an advantage purchased at all. They have said they don't want players to buy advantages over others so that competition for the new hiscores is fair. 2) They advertised the aura as being fully compatible for IM. After 6 hours and selling some packs to IM and including that service, they changed it. There are too many metaphors I can use to make this apparent on why this bad but I think it's obvious enough.
