I don't like timers, at all. I loved PFK but most of its timer were terrible. It's supposed to be a game in which you build your kingdom but you can't really build it because there is a timer ticking.
I see no problem in having the *option* to set no limitations on camping, I just think the "standard" difficulty should have said limitations and that camping supplies are the best option both to have relevant food in the game and to not let the player abuse the system.
The statement "if you don't want to long rest often then don't do it" it's valid only to some degrees. This is a flaw both on the balance and the narrative side of the game for the reasons I mentioned earlier. Sure, I can play pretending it's not there but it really is and if we start thinking that having flaws in the system is fine, just don't use them if you don't like, then all this EA has no point really.
Flaws should be pointed out and corrected, not bypassed.
All the classes are balanced in regard to one another mainly because of their resources and their management. If the game cuts out all the resources management part because long resting has no limits it's a problem. It's fine for the "easy" difficulty, not for the standard one.
