Therefore, players will be able to 
solo their way through level 1 to 15 as a battle class. From 
level 15 to 35, the players will "learn the basics of party play." After 
level 35, we expect some players to really start talking about the mechanics and strategies for boss battles.
Even with the 2.5 second global cooldown, from a newbie standpoint, it's almost impossible to have a conversation during battle. 
Therefore, we intentionally left some extra room during the content (i.e. at the start, before a boss battle, when opening a treasure chest after the boss battle, etc.) to make it easier for players to say converse and to strategize (not including the battles that occur during the main scenario after defeating Ifrit). 
We would like new players to start using the chat after they are comfortable with the game.
Therefore, we're not expecting players to chat during battle until they reach the high-level content. Chat should mainly take place "in between battles," "in between content," "in the city/field," and "during FATE." Of course, 
we expect players to form a party through /shout to have a better chance of beating battle content. While shouting may take some courage, I personally love seeing the conversations that take place via say and shout. I look forward to players talking about item stats, strategies, linkshell/free company recruiting, and general Q&A. We'll do our best to support the players from the system-side and the through the Lodestone. However, please note that no matter how fulfilling the system is, it's up to the players to utilize the system to communicate with other players.
As for the experienced players, please spark up a conversation in between battles and quests whenever you have the opportunity. That is the key to starting conversation within the community!
