Letter from the Producer LIVE Part X: Will the netcode issue be honestly addressed?

[Bixby]

With this netcode players will never see whack-a-mole minigame ;(.

Sure we will. You'll just need to pre-whack.

Lag isn't the issue. The .3s isn't the issue (though it's a large part of it). It's the general lack of lag tolerance that's the issue. Too many things require a round-trip to the server for the client to even respond. There's no reason the server should need to be consulted for spell interruptions. The client knows I'm moving, the client shouldn't even let me start casting. If I've already started, it should be able to stop me immediately, and let the server catch on whenever the heck it catches on. The entire game is just infested with this creeping unresponsiveness that makes it feel clunky, that pulls the player out of the game and into this terrible meta-game of guessing how input is going to be interpreted this time.

But really, I just wanted to say "pre-whack." >.>

It's definitely something on SE's end cuz I know sometimes people get random rubber banding that lasts for a few hours. There's usually someone in my party reporting it at the same time. Then it'll go way and someone else will start getting it. I went though a period of a few weeks after the 2.05 hotfix where I would get it every other day and sure enough, when i asked people there was always someone else getting it. There's no way that It's just a coincidence and that it's on the Client's side. Something on SE's end is causing lag spike for random people.
What's funny is the lag spikes would always go away for me at peak hours. It had nothing to do with my internet; it doesn't do it on any other game. FFXIV usually runs fine for me though. I feel bad for people that have to deal with it all the time.
