If you want to raid, WoW has fights with better mechanics, a better variety of bosses, and less artificial difficulty (need gear to pass a heal/dps check) walls but more difficult and intriguing mechanics. Alexander Savage is a huge improvement from coil imo and a step in the right direction. If you want to PVP, the queue times in FF are longer as there's three factions instead of two, and the PVP is rather bland here. But that's all there is in WoW. A new raid and more PVP every xpac. FF14 has done a good job of bringing a variety of new features every patch... not to mention there's a ton of fan service here. I just find FF14 to be the more fun game. Once 3.0 raid content is over, there will still be things to do. Outside of raiding in WoW I just got bored.
