What does FFXIV get from Final Fantasy XI

Final Fantasy XIV is is pretty awesome.FFXIV Power leveling is a very popular service among the ffxiv players which can make their charactors get a high level in the shortest time. So that's a bright point as well.
It also means that the future isn't what it used to be. The Future consists of patches and expansions and new classes and the like. All good things, all welcome, and all things that could take a few lessons from other games.

As I said before that Final Fantasy XIV was designed to fix some problems from Final Fantasy XI that it never was going to have, but that's not what I'm talking about. Instead of talking about preventing players from leveling consistently or hunting the possibility of RMT with McCarthy-level vigilance, let's look at some simple lessons to internalize in the future:Don't skimp on the tanks and healers.Do go for breadth over insanity.Don't make the game hostile to new players.
