Shrine bases were way different the second time then the first, they upped the speed of the towers by the amounts Orca showed further up. I don’t recall the speeds being as predominant the first time. There was a change for the more difficult.
Not arguing with what you mean, but questioning how you see a speed boost the second TR as easier than the first. You responded with the elements guardians are easy, which is not shrines, trying to get you on the same page.
