iNfo:
In the beta version of the original game, rest did not exist and experience was designed to prevent players from playing more than few hours in a row. Experience gained was divided by 50% after few hours. However, beta-testers did not like it and rest was implemented, giving instead 200% of experience for few hours, which Blizzard's developers later reported as being the "same numbers seen from the opposite point of view"
The iNfo portion of this is what you should take home children. That's exactly what this system is, "fatigue" renamed. Either way who the hell cares it never stopped anyone from anything. People used to hammer away at their classes fatigue or not consequences be damned. Now will be no different.
