Alright, level 25 is when the last of a caster's spells maxes out (Correct me if I'm wrong) But It takes to level 25 to get Greater Magic Weapon to +5. Perhaps it should be considered to cap the resting time here as well; to give some sense of equality?
It we want to go down the biological route, then staying awake for 3 days straight would have penalties to all attributes, skills and saving throws. Do we really want to go down this road?
Yes actually. I find it very creepy and unbalancing that fighters and rogues NEVER have to sleep and just keep wandering around, applying infinite healing kits to themselves without suffocating under the bandages or passing out from exhaustion. At least spellcasters get "tired". This is unbalanced.
That only spellcasters suffer is wrong. what about paladins (not the spells they use I am talking about the feats) Arcane Archers, Babarian (rage), Dwarven Defender.... and and and... They all have abilities that are limited to x-times / day.Not only casters have that. Most Arcane Archers have a split where the caster class only has the rwuired 5 or a few more levels. So they suffer from short spell duration of weak spells and their special abilities are limited aswell.
