Noaki Yoshida in one interview told that if players are bored with the game or if they have completed all PVE content then they should take a break and come back in the next patch. Frankly speaking this is very damaging to the game and to square enix as a whole because its an mmorpg and players play mmorpg to commit long term. Look at the WoW director, Ion Hazzikotas. He never told players to take a single break from WoW. Infact he gives players new ideas on how to play WoW differently when they get bored or during a content drought but never once he said to take a break.
When I play an mmorpg I play it non stop for 10+ years without taking breaks and I am sure there are millions of players like me who think the same way. Majority of mmo players have no interest in single player games.
