Races:
Hyuran (hume)The Hyuran are said to be the most prolific race of all Eorzea. The article mentions that they migrated to Eorzea in large number from neighboring islands and continents. They brought with them great technology and innovation that raised the civilization of Eorzea to new heights. Having immigrated from a variety of lands there is great diversity to be found amongst the Hyuran in terms of language and culture. The two main classifications of Hyuran are "Midlanders" who migrated 
to lower areas of Eorzea, and the "Highlanders" who migrated into the hills and mountains.
Elzen (Elvaan) The Elzen are the anscestral race of Eorzea, and have clashed with the Hyuran in the past to defend their homeland.
Lalafell (taru) They are a race of farmers who live mainly near the Southern Sea. They also boast an exceptional degree of intelligence.
Roegadyn (galka) The Roegadyn are a muscular race of fishermen that live near the Northern Sea. It appears that some work as hired mercenaries or bodyguards, but others lead a less noble life as pirates.
Miqo'te (Mithra) Miqo'te are cat-like people who are again known as fierce hunters. They are mainly separated into "Sunseekers" and "Moonkeepers," the latter of which are 
nocturnal. Together, the Miqo'te are a minority race in the land of Eorzea.

FFXIV Game system:
Armory System depending on a character's equipment dictates play style. Changing equipment is executed in real time. For example, if you're invited to join a team of warriors to fight the enemies, you only need to wear the corresponding equipment to be ready. Once the party disbanded, you only need to change equipment to come back as a crafter, fisherman, etc.This freedom will make the solo play easier since a warrior who wants to be cured can change into a healer himself. It's crucial to maintain a good balance of equipment to "level up" easier and be less reliant on other party members.
