The more I read random ideas about length of an adventuring day, the more I want infinite resources. When you rest, you regain all your hit points, powers, everything. You're ready for the next encounter. Go! No daily powers. No healing surges. You run through as many encounters as you need to, to get your adventuring day done.
I know, there is supposed to be a resource management game within D&D. But I'm tired of it. I don't want to keep track of it. I just want to adventure, interact with new environments, new NPC's, new foes, I want to save damsels in distress, chase after thieves and brigands, investigate haunted houses, siege castles, lead nations, walk through hell, and kill gods. I don't want to count how many charges are left in my wand, how many arrows are in my quiver, how many surges (fine, hit dice if you must) I have left, how many dailies I have remaining.
What matters to me most, is being in the moment. I don't want to worry about how many times I cast fireball today, and see if I can squeeze out another one when a horde of gibberlings is coming at me. I don't want to worry about standing around, sucking on a healing wand before I run up the stairs of a burning building to save a mother and her child. I don't want to get to the doorstep of the big bad demon, and yell through the door, sorry buddy I'm out of healing, gotta go, I'll fight you tomorrow. I want to Just Do It.
There is also real life time constraints. We might have 3 weeks between sessions. If we're on the same adventuring day, it might mean I'm not going to cast any fireballs today because I cast one last session and I'm out. I've been out for 3 weeks, I WANT to blow something up!
Don't get me wrong, I'm happy to play the resource management game, it's a large part of tactics we use, and I enjoy tactical play, but I'd be happier, if the resources were confined between short rests, rather than extended rests.
