I have no illusions that this will ever happen, but here's my suggestion:
Lower the +Damage of Fulcrum Shift.
Add +Regen +Damage and a small +Defense bonus to Inertial Reduction.
It'll never happen, but I think it would be an improvement.
EDIT: Instead of +Regen, give IR an amount of +Dam almost equal to what is taken from FS. This keeps overall performance almost identical to current, but moves some of that power earlier so the set isn't so reliant on FS.
