Oh noes, mankind comparing something they are experiencing now to something they have experienced in the past. Oh my fucking god we better stop recording temperature and stop giving out record lows and highs because its totally ruining the extent to which I can enjoy today's weather.
I think in the future the game's spells/abilities will go a step further and maybe drop from high end dungeons. Maybe Inscriptionists will be able to craft and sell lesser versions of those spells, but the best kind will drop from raids.
Hopefully some time in the near future adventurers who have killed everything from Lucifron to Illidan+ will finally have greater knowledge of their class than some level 50-60 gnomes and dwarves in Ironforge who will run the other way when faced with any of the adversaries that player characters have dealt with.
