I can think of one possible reason I'd close my account (but it's so easy to avoid, which is why I'm not quitting):

Voidwatch.
Voidwatch.
Voidwatch.

More remnants of an old FFXI where timers rule the day when it comes to voidstone restock. The content overall is a joke - oh, let's spam procs and ride Fanatics to victory! - while being on my BLU is a waste of time because I'm a proc-bot. It's embarassing the way the drop system works too. Thankfully, I'm never feeling obligated to do content like this so I simply avoid it and move on with other activities.

I hope in the coming months this content is either fixed to hell or thrown out a window and into a pit of fire. It's a joke.
