Alot of ppl have been experiencing lag with this game lately (see the 'throttling' thread and others)

I'm with a different service provider and have been experiencing severe lag, mostly during the day, since xpac came out. Been trying stuff to possibly help get rid of the lag, but no luck. Not yet anyway.....if ever.

I'm on PS4, and like you said, Final Fantasy XIV is the only thing on my network that is giving me problems with lag.
