The peopl trying to explain the fatigue system are not understanding the actual problems with the system. They do not have anything to do with how much SP you are missing out on.

1.) Fatigue is hurting interest in the game. Some may not care about the players that would play FFXIV, except for Fatigue. I can't even convince my friend to give it a shot again.

Me: "Check out FFXIV again. It's still free and they are improving it."
Friend: "Does it still have fatigue?"
Me: "Yeah"
Friend: "Geez what a dumb idea. Let me know if they take it out."
Me: *sigh*

2.) Fatigue does not keep hardcore players from reaching level cap.

The next person who wants to defend the Fatigue system, please do not dicuss the amount of penalty. For the sake of a healthy discussion, please respond on the points of:

1.) Players who wil not play/quit FFXIV because of fatigue.
2.) The effectiveness of the system in holding back hardcore players.

IMO, the system may not be horrible, but it's drawbacks far outweigh it's usefulness. It does more to hurt the game than help it.
