I don't either. But I DO think that removing the event-triggered free instant yields will make a big difference.Regarding all the comments about Deity being too easy - I honestly don't think removing their unit supply bonus is going to make that much of a difference
While I would be quite glad to see them removed, I do think they need a replacement. Using "replacement" very loosely, since the replacement doesn't need to be even in the same category. Just anything to up the difficulty.
that said, "make Deity (and Immortal) harder" can very easily just be a separate proposal
