I suggest to you an idea about resting that I have been thinking about since viewing another topic recently about "OOC resting", where the duration of the rest was requested to be longer to prevent sleeping in public for ooc reasons. This is my suggestion to counter it and hopefully make a better case for the kinds of rest you can take.
To preface, I am not entirely sure what the benefits should all entail when one gets "better rest" or "normal rest", but I want to put forth the following. Right now, when you rest you are given options. These are to Pray, to Sit Down, to Sleep, and to Study your Spellbook, and these actions last a few seconds and poof, you're rested. There might be more, and they are class dependent. I am not sure implementing an exhaustion system that requires you to take regular rests is the way to go, i like the hunger, thirst, and exhaustion system we have now, but a function to get better rest could encourage people to RP the need to sleep more often, depending on how long it was that you had a good night's rest.
I suggest that the options do different things. While Praying/Studying/Meditation is good to restore your spell uses, Sitting down should go a step further because you are actually resting your body and mind and being sedentary. It should last a bit longer maybe, and offer you a rested feeling, whatever that means, maybe it can be necessary to process your xp like the food system is.
And on the subject of Sleep, where your character literally lays down and takes a nap, this should be longer and give better benefits. I am not sure of these benefits. Maybe a long time without can cause negative effects like spell failure or removal of the take 20 rolls when using skills.
Suggestions? Thoughts? I think we could do more with the rest features. What about you?
