How is FFXIV like Wow you ask.

WoW implemented Transmorgrification which allowed you to use the appearance of a piece of armor of similar type in place of the item model you were wearing. That feature is in widespread use after your first 50 in this game too.

Instanced lock out raids which require visiting the dungeon first again something that was not present in FFXI, but was required in WoW from Vanilla and daily quests.

Another favorite of mine Collectable mounts again wow did it first, up till now every ff title has exclusively used the good ole chocobo.

Another great similarity WoW's tag loot system, implemented in Mists of Pandaria allows players to loot the same NM or rare kill regardless of faction or party just by tagging or attacking said nm or rare in the field while it is being killed.

The ability to jump freely!!! nuff said something ffxi needed for years. Also projected flying mounts.

There are other similarities
