Can you explain why you think the system is perfect? What do you like about it? (Seriously asking here. We can't have a discussion unless you provide reasons and arguments, and who knows you might convince some of us to change our minds)
Press long rest button -> all resources restored -> happy mind, let the adventure continue. What's the problem? You want to take a shower and shave beard or what?
So you're fine with companion dialogue being restricted to long resting?
And that the ease of long resting means that spellcasters are now much more powerful than martial characters?
And that you can fast travel back to camp in the middle of a dangerous area, long rest, then come back fully rested and fully restored, removing a lot of the tension of dungeon delving?
