i dont want them to completely get rid of loot scaling. I want it to make people in parties get MORE loot

and make henchmen not take loot as much.
In a full party of 8, you should see the loot drops that you used to see for solo farmers, split amongst 8 people. in solo farming, you should see 1/8 the drops of a full party. basically, loot dropping on a per-person basis instead of scaling would be best I guess. This way whether you solo or group, you get the same amount of loot. everyone wins except gold sellers.
You have to admit, a solo person getting MORE loot than a whole combined group, with an actually easier experience thanks to certain gimmick skills, was way too much.
