Thank you for your response.
I think it does address the first issue in part. If you can’t make progress during your payout hour because the shard group knows when you are advancing, you can attack at another time within the 24 hour window approach. This also gives players a lot more freedom. As you can attack when you have the free time during your day instead of at one set window. I know CG has given us the option to move our payouts 2 times a year, but that only offers limited flexibility.
Example: I had a 1pm payout initially, and could not make progress, so I switched it to 7am. Had great success (rank 1/2 payouts) for a few days till the shard learned my new payout... and then back to limited progress (sub 10).
I could switch my payout again but then it’s locked for the year... this doesn’t give me the flexibility to be dynamic in my attack time that would let me work around a hostile shard group. The 24 hour window does.
I acknowledge that that there would be an increase in number of top payouts but, but I doubt it would be significant as you still have to fight to Rank 1.
