Vanilla WoW was quite a long time ago... but I'm pretty sure it was always there.

Update: it didn't exist for a while in BETA


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"
