It’s still not a reasonable solution, and it wasn’t the last time you proposed this.
For that almost-never-seen mythic level Deed task on the adventure board? You get 9 colored Deeds plus 2 Imperial Deeds in return for beating all four battles. If you revise that payout so that there’s a Book of Deeds as the capstone prize, you’re increasing the rewards by at least a factor of 5 and probably more than that. And while the ending battles in that particular task would be too much for less advanced players, it’s not something that would be five times more difficult than it currently is, assuming it’s made more difficult at all.
If you ask for the sun and the moon and half the constellations in the night sky and a couple of passing comets sprinkled on top, the developers won’t have any problem dismissing your requests as unreasonable and unworkable. So if you really want more Deeds to filter into the game, you’re almost certainly better off asking for incremental progress and improvements rather than trying to build Rome in a single day.
You get 4 Deeds from the Epic-tier task. You get 6 + 1 Imperial from the Legendary-tier. You get 9 + 2 from the Mythic tier.
Bump those numbers up a bit, but I don’t see how your request for such a massive jump possibly returns the results you’re looking for.
