Final Fantasy XIV's maps, which are long on flavor and in-game writing and a bit short on what the various symbols actually mean. So the most recent developer dispatch on the official player site has clarified the symbols on the map and helped explain where to find crucial information.
In addition, the dispatch covers the game's strength-indicating icons for monsters, as well as the intervals for new quests. There are also unlocking intervals for new class-specific guildleves, both regional and local. It's a good incentive to continue leveling a few classes instead of dabbling too broadly, something that's a definite possibility with Final Fantasy XIV's permissive cross-class system. Take a look at the full dispatch for more details on the most recent round of developer-answered questions.
