Yoshi himself looks at WoW for inspiration...even made the Dev team play WoW. We should be thankful to WoW for what we have, and hope Yoshi continues drawing inspiration and learning from not only WoW, but every game on the market - be it a failure or success.
It's extremely fair for the player-base to examine what WoW is doing successfully and suggest XIV use it as a template for new content. It happens in every industry, and it needs too or you'll fall behind.

(Also personal loot was added into WoW in 2012, XIV had personal loot in 2010)
