Because you had a much easier time advancing levels here. The point of transferring would be if you are not the kind of player we are trying to design LunarForce for. You don't need to transfer if you don't want to.
Because ShadowCores has too many players and LunarForce needs more players, when we opened transfers to LunarForce the idea was to never let anyone transfer back to ShadowCores, but since not everyone is going to like the changes we may be introducing here, we're giving them that option at the cost of 60 shop coins.
