New Variant - Defense Measures

I'm trying to do the patron versions of this variant and it's too unforgiving. You have percentage based all party damage that ramps up as the time goes on and multiple segment hit based bosses combined with restrictions on what champions you can use. It's not Idle at all because your party wipes without a lot of manual ultimate spamming or leveling up your champions to keep them alive. This one feels it was released without anyone testing it. I challenge one of your employees to do this variant at a patron level and comment to me that they completed it without pulling their hair out. Fun concept but not fun in actual game play. You can't even offline progress it without it stopping before the target area. My suggestion is to tone down the damage where I don't have to kill the bosses in less than 3 seconds.
