I think the gem generator removal is a good idea most of the time. It forces a more active role on everyone and does remove some emphasis from massively boosted globals and huge hordes of summoned armies that are not in any way tied to actual gem income.

It does make the position of underdog more challenging, but there must be other ways to compensate for that, such as diplomatic efforts.

Of course, that depends on what you like, but I have no objection to less gem gens, especially less clams.
