I don't get your logic. Imagine they cut down on the Declarations lasting only 7 days how Haste mentioned. How are you going to destroy core 4 or 5 ?
I agree with Haste the situation was disproportionaly favouring the attackers, now it does the some to defenders.
Honestly if anything, the bases should be quicker to die, but the declarations shorter. F.E: You have 7 days to kill the base.
Core 1 should die if you damage it 2 times in 4 days
Core 2 should die if you damage it 3 times in 5 days
Core 3 should die if you damage it 3 times in 4 days
Core 4 should die if you damage it 3 times in row
Core 5 should die if you damage it 4 times in a row
also, nerf the GB Guns. GBs should really only reach max damage in a large pack in a long time.
