Sorry you’re not getting the enjoyment any more but at least it leaves more room for us 4* players

I probably play 4 hours a day and have been playing for 695 days. The countless hours argument is a cop-out to me.

It’s a problem with the scaling system in general which has been in place since 5* characters were introduced. It is not new.
