Tier points changes

Does anyone know the aswer to this?
In the latest iFLY, they state that the teir point levels for moving up are reverting back to the original figures.
Why did they change them in the first place and why have they noe gone back to the old levels?
Does anyone see them reverting back to the more "interesting" figures again?
