And like a billion other additions too
Final Fantasy XIV: A Realm Reborn patch 2.1 has hit bringing with it a ton of new stuff. Notably the first installment of the Crystal Tower 24-man raid. Additionally there's a new housing system for free companies, rebalanced job actions, over a 100 new quests for those at level 50, and more.
Plus, there's new dungeons, changes made to FATEs, and well it's actually kind of nuts scrolling through all the additions and changes on the patch update page from Square. Hell, the preview video is even ten-minutes long! Needless to say, there's a ton of stuff to bring you back for more.
