Thank you for reading this!
I understand completely that you are dropping cups to make sure you can fill up the much needed chest nice and easy and with some speed to it.
But could you please also conssider the people that should be on the level of cups you decide to fall back to? These poor bastards work hard to go up in cups only to see that everybody around them is a lot stronger teams putting up to defend their cups and hams!
For myself my max team is 2800 (ish) and I raid in gold.
What I now more and more notice is that people with full 5* teams are around 1200-1400 cuprange.
No need to say that people that do fight hard for their cups and try to go to normal levels for the team they have, do not stand much chance of filling the chests nice, easy and swift the way you can do.
So what you might do: leave a team that can be beaten if you want to go lower. You can easily hit back to gold if you ever might get hit below 1200 cups before cashing the chest.
