I despised the rest system in POE1, and I think DF's system is much better.
But I'm not opposed to limited resource management. If, for example, I had 3 days to complete a dungeon before it caved in, resulting in the loss of any items in it, and even a TPK if you were in when it caved, I'd consider that very interesting and challenging.
My gripe is with systems that offer limited resource gameplay but are too cowardly to have actual consequences or failure states for mismanagement of those resources.
In POE1, if I expend too many spells due to being weak or lacking skill... oh noes, I have to go back to the tavern to buy resources that cost fuck-all, wow this is intriguing gameplay guyz.
