It might help our understanding of the problem if SE published a breakdown of Gil holdings of various players. Let us see how many people have holdings in the 900,000,000 to 999,999,999 range, 8000,000,000 to 899,999,999 range ect. Let us see if there in an inordinate number of people in the upper brackets. If there is then, just maybe, there is a justification to this partial Gil wipe.

Even if there is SEs current planned server setup does not justify a 90% reduction for everyone. The only way a 90% reduction can be justified is if we were being allowed to join any server of our choice. That way new players would not be placed at an extreme disadvantage relative to existing players.As it is we are being restricted to existing servers with existing players and existing economies. Depending on how SE plans to construct Gil making opportunities there will still exist a disparity between people at the high end of Gil holding and those at the low end. If the breakdown of holdings justify it then cap the max holdings at launch to 99,999,999 but let everyone keep what they earned up to that point, as originally promised. Anyway you go this is still a poorly disguised partial Gil wipe.
