In the top tier you were forced to spend them against most (if not all) fully boosted +4500 trophy bases.
I’ve been playing for almost 2 years and only ever had to use scrolls in “desperation mode” (when you’re about to die or time is running out) or in dungeons.
This time, during Conquest, scrolls just became a regular part of my attacking routine. Most times I already knew I was going to use a scroll right at the start of the raid (barely outside of my tent) and then, hopefully, I would not have to scroll a 2nd time against the beast.
I think I spent close to 1500 gems during Conquest and from what I saw on battle reports and talking to other people, I’m guessing I did better than most.
This bug was really brutal on the top tier.
