I do not agree that this is a requirement, I see that you do. I had seen you make this balance claim before. I was interested to find out what you were claiming, and I now believe I have an understanding. I still do not see the need to dump the daily XP into a single encounter as I have never seen a group really balk at 3 or 4 encounters and the daily XP allotment can be meet with that encounter allotment.Game balance in 5e is centered around resource management. If they are not using up all or very nearly all of their resources, they were not challenged.
Thanks for the conversation.
