Zos wants you to grind, Zos wants you to visit older zones, Zos is adding more and more reasons for players to re-visit older content to make the game look more appealing to newcomers.
The sad truth is though that the majority of changes and additions are actually forcing a lot of veteran players to quit rather than what Zos is aiming for.
LMAO, I am a veteran player....endeavors are not going to force me to quit.
