I do not know how scaling works on mayhems 1-3
Generally we’re advised to turn lootsplosion off as enemies drop normal lvl 57 gear/non mayhem.
I thought mayhem 1-4 was all normal lvl 57 stuff myself.
I personally only play at mayhem 10. I turn mayhem off to farm for class mods as theres no difference.
Personally i see no difference in drops. I dont notice more cash. Even vendoring items or dropping in general.
Hotfixes have done weird things over the course of the events. Id notice.more world drop. legendarys one week. Dedicated loot monsters droped. Blue green or purple. Takedown. First tawldown patch post mayhem 2.0 dropped shields properly but wotans loot wasnt there. They patched it and i get usualy world drop trash and i got class mods only one run. At m10.
The amount of legendarys that fly out is the difference.
Farming freddy i noticed a few legendsrys on. Normal jack gave 4-5. Turned on mayhem and the count became 1 or 2. Eventually thered be a run with one leggo or purples n blues.
Its noticeable. Though recently dlc dedicated drops have become better.
So thats an improvement. Ita really really weird and i hope they clean up the tables properly.
Ive documented this overtime in manu forums with pictures here. It’s just weird.
But in general mayhem does not mean increased anything but enemy health to me.
