Adventurers gaining xp solely from killing monsters (not counting the occasional "story" or quest xp) irks me.
Do you think an additional 1xp for every 10gp of loot acquired would seriously unbalance 5E's rate of advancement?
I still remember my multiclass fighter/thief back in 2e. With gold for Xp, I was 5/5 when the party was about 6th due to my excessive looting and pick pocketing.
Those were the days!![]()
