Please Fix It

I ran into a problem. I decided to start farming in the Expedition League in this league.
However, there were many problems.

Too much immunity to elemental damage, chaos damage, and physical damage. I use all the Expedition League scarabs, as well as a large node in the Atlas tree - extreme Archaeology, and if there is a scarab for additional suffixes and prefixes. 70% of the maps simply become impassable due to the presence of either immunity in the center or in all places at the same time, which simply forces to throw the map :(
And also, if there is no immunity, there is a problem with damage reduction and avoid damage from hits, which often exceed 100%. Sometimes monsters of the expedition have a health regeneration of more than 100% every 4 seconds, which is not enough damage even for strong build. I can easily kill uber bosses, but I can't kill the magical monster of the expedition.

There are several possible solutions. Or make scaling of expedition mods smoother (with decreasing usefulness - this will smooth out their regeneration, reduce damage received and avoid damage from hits).
Also, when choosing a large node - Extreme Archeology - exclude the presence of monster immunity. So with endless immunities, it makes no sense.

Thanks!
