The difficulty of Normal Content in this game needs to increase.

Push people out of their comfort zone, Slowly increase the difficulty of content as the expansions go on.

I remember when WoW tried this at the start of Cataclysm with the hopes that players would rise to the occasion, but instead they just threw tantrums until everything got nerfed into the ground again.

Unfortunately the problem here isn't the devs, it's the players. People say they want more difficult normal content, then when it happens they complain until it gets nerfed like Orbonne.
