Nope, the greatest enemy is the players.
How so? All the players do is pay the subscription fee and play the content they give us. The company behind it are the one that make or break the game.

Do you think they would of increased the level cap to 99 invalidating all current content, made leveling really easy to the point people will have nothing to level soon, make merits easy to cap, and wipe 8 years of endgame content off the game if FFXIV had not been made?
